3. Principle of operation
The handwheel on Camflex® II is designed to be
used for emergency action only.
The concept of the Camflex® II valve is based on an
eccentrically rotating spherical plug contained in a
free flow design ANSI Class 600 body. The plug
seating surface is joined by flexible arms to a hub
which slides onto a rotating shaft. The plug is free to
center itself along the axis of the shaft. A positive
seal between plug and seat is achieved by elastic
deformation of the plug arms. The chamfered seat
ring is fixed in the valve body by a threaded retainer.
The actuator is generally mounted with air-loading to
counter the dynamic torque on the plug. In figure 2
the flow direction tends to open the plug and the
actuator is oriented to close it with increasing air
pressure. The actuator spring force assists plug offbalance forces to open the valve on air failure. If the
valve is to close on air failure, the body would be
turned around in the line so that flow tends to close
the plug and the actuator position would be reversed.
The plug and shaft are rotated through an angle of
50° by a lever linked to a powerful spring-opposed
rolling diaphragm actuator.
The Camflex® II valve has a modified linear flow
characteristic, which is the same in either flow
direction. It can be easily transformed to an equal
percentage when equipping the valve with a
positioner 4700 series, 8000 series, SVI (Smart
Valve Interface) or FVP.Reduced TRIM factors 0.4
and 0.6 are available on all sizes. The flow capacity
of a 0.4 factor is 40% of the nominal capacity of the
valve and it is 60% for the 0.6 factor. Factors 0.1 and
0.2 are available on the DN 25 (1") valve.
The solid disk-type handwheel and locking lever,
provided as standard features on the Camflex® II
valve and are mounted on the yoke opposite the
actuator. The handwheel may be used as a manual
actuator or as a limit stop. A threaded hole in the
opposite side of the yoke accommodates a cap
screw and locknut which may be inserted as a limit
stop in the other direction, or in combination with the
handwheel to lock the valve in a selected position.

The ability of the Camflex® II valve to handle a wide
range of process fluid temperatures is due to the
long integrally cast bonnet. This affords ample
radiation surface to normalise the packing
temperature. Therefore, with self-lubricating TFE
Aramid fiber packing, the valve handles
temperatures from - 200°C to + 400°C (-320°F to
+750°F). When insulating the valve, do not insulate
the body neck (see figure 3).

E. If the valve is to be installed in a horizontal
position, install the lower flange bolting to
provide a cradle, which will help support, the
valve while installing the remaining bolts.
4. Unpacking
Care must be exercised when unpacking the valve to
prevent damage to the accessories and component
parts. Should any problems arise, contact the
Masoneilan Representative or District Office.
F. Place the valve in the line.
G. Select and install correct gaskets.
Note: Spiral wound gaskets, suitable for service
conditions are recommended.
Note: For ease of shipment and to prevent damage,
valves equipped with the spring diaphragm actuator
are shipped with the handwheel unassembled. Refer
to section 10.3 for handwheel assembly procedures.
H. Insert remaining flange bolting insuring that the
bolts align with the special bosses on the body,
which assure the valve is centered in the line and
also prevent rotation.
Note: For certain flange standards, through
bolting is not possible because of the valve body
neck or bonnet. To accommodate flange bolting,
guide arms with threaded holes or slots are
provided on the valve body to receive flange
bolts (refer to figure 22).
5. Installation
The Camflex® II valve has been assembled at the
factory in accordance with specify instructions
concerning flow direction and actuator mode. The
valve must be installed so that the controlled
substance will flow through the valve in the direction
indicated by the flow arrow (25), which is located on
the upper part of the valve body neck. The valve
actuator should be installed so the actuator is above
the centerline of the shaft. To install the valve in the
line, proceed as follows:
I.
Tighten flange bolts evenly and firmly.
Cantion: If the valve is to be insulated, do not
insulate the valve body neck.
Note: If the valve is equipped with manual
handwheel, it may now be placed in service.
Caution: Any change in flow direction or
actuator mode must be accomplished as
outlined. In this instruction otherwise
equipment malfunction could result.
6. Air Supply Piping
Air is supplied to the actuator through the 1/4" NPT
tapped connection in the diaphragm case. Refer to
figure 14 to determine the correct supply pressure
and tubing size, then connect air supply piping.
A. Check the model number on the serial plate (56)
against the numbering System described in
figure 1 to determine the valve mode.
B. Clean piping and valve of ail foreign material
such as welding chips, scale, oil, grease or dirt.
Gasket surfaces should be thoroughly cleaned to
insure leak proof connections.
Caution: Do not exceed maximum air
pressure indicated. Personal injury and
equipment malfunction could result.
C. To allow for in-line inspection, maintenance or
removal of the valve without service interruption,
provide a manually operated stop valve on each
side of the Camflex® II valve with a manually
operated throttling valve mounted in the by-pass
line.
Note: When the valve is equipped with regulators or
other accessories supplied by Masoneilan, only
connections to those accessories are required since
the piping to the actuator is connected at the factory.
Some valves equipped with electrical accessories
will require appropriate wiring. Refer to
manufacturer's instructions for correct wiring
information.
Note: If a flanged Camflex® II is being installed
and the distance between flanges is established
by ANSI or DIN, spool pieces (spacers) are
inserted between the line flange and the valve
body flange. Gaskets and valve bolting are then
installed and torqued using standard flange and
line bolting criteria.
7. Placing in Service
D. For flangeless valves, refer to figure 23 and
determine the correct size and quantity of bolts
to be used for the valve and flange rating.
With the valve properly installed in the line and all air
or electrical service connected, it is recommended

orientation and the actuator to yoke orientation be
marked in relation to each other. This will simplify
reassembly.
that the valve be run through one cycle to insure
proper functioning. Proceed as follows:
A. Back off the handwheel (53) so that it will not
interfere with the operation of the valve and
tighten the handwheel lock (52).
A. If required, remove the valve from the line.
B. Remove rear cover (29) and front cover (32) by
removing the two cover screws (30).
Note: If the valve is equipped with the optional
limit stop (77), it should also be backed off to
prevent interference with the operation of the
valve.
C. Remove bottom cover (11) and spring barrel
boss cover (58).
D. Remove indicator (88) by removing the two
screws (89).
B. Apply correct air pressure to the actuator.
Note: Valve should function smoothly and with
maximum pressure, the valve indicator (6)
should show full open or full close depending on
valve mode.
E. Loosen handwheel lock (52) and turn handwheel
(53) so it does not interfere with the movement of
the lever (34).
C. Relieve air pressure and return valve to normal
mode.
Note: On valves supplied with the optional limit
stop, (figure 17) loosen nut (78) and back off the
limit stop screw (77) so it will not interfere with
the movement of the lever (34).
D. Gradually open process lines to place the valve
in service.
F. Connect an air line to the actuator supply port
and using a manual loading panel or regulated
air supply, apply enough air pressure to the
actuator so the lever will move to an intermediate
position.
E. Check for leaks. Repair as required.
Caution: Always insure process pressure, a
pressure and electrical service are off and the
valve is isolated and relieved of pressure
before performing maintenance on the valve.
Caution: Do not exceed pressure listed in
figure 14 for actuator used. Do not use
handwheel to move the lever.
F. If desired, the handwheel may be used as a limit
stop. Set in desired position and lock.
G. If the optional limit stop (77) is used, set and
tighten locknut.
Note: If the valve is to be reassembled using the
same orientation, it is recommended that the
yoke (33) and lever (34) alignment, in the closed
position, be marked to simplify reassembly and
alignment of the lever and shaft to insure proper
valve functioning. See figure 17.

BODY S/A
(Refer to figure 16 and figure 17)
H. Remove clevis pin (7).
I.
Maintenance required on the internal components of
the valve or re-orientation of the actuator and body,
requires that the actuator and yoke be removed from
the valve. On the 6", 7" and No 9 actuators, for ease
of handling and reassembly, it is recommended that
the spring barrel be removed from the yoke and then
the yoke separated from the valve body.
Relieve air pressure from actuator enabling
clevis (35) to disengage from lever (34).
Note: If the valve is equipped with a positioner,
refer to the appropriate positioner instruction for
procedures on cam or lever removal. Then
proceed to step K.

Caution: The purpose of the safety pin is to
prevent the shaft from being pushed out if the
yoke is removed while the valve is still
pressurised. The internal components of the
valve cannot be removed without first
removing the safety pin.
Note: With body secure, grasp lever and yoke and
separate. Yoke, lever and packing flange are
removed at the same time. The yoke may have to be
struck with a soft face mallet to break it loose.
8.2 ACTUATOR COMPLETE
DISASSEMBLY
D. Pull on the shaft (19) to remove it.
Note: Difficulty is sometimes encountered when
removing the shaft from the plug mainly due to
an excessive accumulation of deposits between
the plug splines and the shaft. Application of heat
to the plug shaft bore while using one of the
following methods will facilitate removal.
The spring diaphragm actuator used on the
Camflex® II valve was designed basically as a low
cost
non-replaceable
item
and
therefore
disassembly is not recommended. However, in
some instances and for emergency purposes,
disassembly may be required. Proceed as follows.
Caution: When using heating devices. Insure
that proper safety practices are observed.
Such items as the flammability and toxicity of
the controlled substance must be considered
and proper precautions taken.
A. If the actuator is not removed from the body
proceed to the paragraph 9.1 A. to 9.1 L.
B. Loosen locknut (46) then remove the clevis (35)
and the locknut (46).
C. Loosen and remove capscrew (41) and remove
diaphragm case (42) and diaphragm (40).
If the shaft is not removed easily, replace the
lever (34) on the splined end of the shaft (19), tighten
the lever capscrew (49) and using a mallet, tap the
lever (34) as close to the shaft as possible and
remove the shaft (19).
D. Using a deep socket, loosen and remove locknut
(45) and washer (44).
E. Remove piston (43) and spring (39) and inspect
all components.
Note: If the shaft cannot be removed by tapping the
tightened lever, figure 20 illustrates an alternative
method of removal. Using a pipe nipple of suitable
size and length and reversing the packing flange and
stud nuts as shown, the shaft may be jacked out of
the body. For larger valves the use of an additional
washer and nipple to assist in holding the tightened
Lever is recommended. The lever should be
tightened at a point where the hub on the lever is
flush with the end of the spline.
F. Proceed to section 10.2 for reassembly.
8.3 VALVE BODY (Refer to fig. 4 & 16)
Maintenance to the internal components required on
the Camflex® II Valve can normally be easily
determined since the seat ring and plug can be seen
once the valve is removed from the line. Although it
may be determined that the seat ring does not need
replacement, it must be noted that the new plug and
seat ring must be lapped thus requiring the
disassembly of the body. It is recommended that
both seat ring and plug be replaced if one or the
other is damaged due to service.
After the actuator has been removed from the body,
disassemble the valve using the following
procedure:
E. The components which should come out with the
shaft (19) are: the packing (17), packing box ring
(23 or 100), spacer tube (20) and upper guide
bushing (21).
Caution: Prior to performing maintenance on
the valve, isolate the valve, vent the process
pressure.

wrenches be purchased or fabricated to facilitate
removal and reassembly of the seat ring (2) since
SPECIFIC TORQUES MUST BE ACHIEVED to
obtain tight shutoff and insure proper functioning of
the valve.
Note: The spacer tube (20) and upper guide
bushing (21) may remain in the body. They
should be removed. The spacer tube (20) can
only be removed by pulling it out the bonnet end
of the body. The upper guide bushing (21) may
be pushed through the body after removing the
plug or pulled through the bonnet end of the
body. On valves designed for use on slurry or
viscous service, the upper guide bushing has an
inner "O" ring (92) and an outer "O" ring (93) and
the lower guide bushing has inner "O" ring (95)
and outer "O" ring (96) (Refer to figure 4).

A. Secure the valve body in a vise or appropriate
holding device with the seat ring facing up.
Note: A groove is provided in the bushing for
prying out the bushing using a screwdriver. If the
bushing will be pried out it should be pried from
two sides to prevent jamming the bushing during
removal. If the bushing does not come out easily,
fill the bushing with grease, insert the shaft (19)
into the valve insuring that the machined portion
of the shaft starts into the lower guide bushing.
Using a soft faced mallet, strike the end of the
shaft lightly until the bushing is pushed out
partially. Remove the shaft and complete
removal of the bushing by prying out using the
groove provided.
Care must be taken to avoid damage to the
gasket face on the valve body.

lugs.
C. Engage the retainer wrench with an impact
wrench or suitable wrench and loosen, then
remove retainer (3) by turning counterclockwise.
D. Lift out seat ring.
Note: In an emergency, drifts may be used to
remove the seat ring retainer. However, two
drifts should be used and placed in the slots 180°
apart and struck simultaneously.
Caution: Do not pry the bushing using the
seat for leverage. If the bushing cannot be
easily removed, proceed to section 8.3.1 and
remove the seat ring retainer and seat ring
then remove the bushing. Place a piece of
soft stock (brass, etc.) between the inner seat
shoulder and prying device to prevent
damage to the seat sealing area of the body.
8.3.2 DVD Removal (Refer to figure 16)

9.2.2 Soft Seat
Do not lap the soft seat ring to the plug ; however, the
seat ring must be lapped to the valve body. The
procedure for lapping the seat ring to the body is the
same as stated in items A. through D of section 9.2.1
on Hard Seats.
A. Determine correct valve to actuator orientation.
B. If required, reposition body studs (28) and
packing flange studs (13).
Note: Depending on the actuator position, insure
that the body studs (short studs) when placed
through the yoke holes will be positioned in the
front of the yoke opening for ease of accessibility.
9.3 YOKE ASSEMBLY (Refer to figures
16 and 17)
C. Insure that grommet (12) and shaft bearing (8)
are in the yoke. Turn shaft so the plug is in the
closed position.
Maintenance required on the yoke (33) is limited to
replacement of the grommet (12) and the shaft
bearing (8). To replace either, the actuator must be
separated from the body. (Depending on the type of
actuator used, refer to appropriate section). Insert
the grommet into the yoke with the recessed part of
the grommet towards the shaft bearing. The shaft
bearing (8) is slip fit into the yoke and is removed by
pushing it out towards the grommet.
D. Slide the valve shaft partly into the lower yoke
opening, allowing enough room to place packing
flange (14) over the shaft (19).
Note: Packing flange (14) is placed on the shaft
(19) with the concave side toward the valve
packing (17).
E. Insure slots in packing flange (14) line up with
packing flange studs (13).
Caution: Insure the bearing seat in the yoke is
clean. The bearing should slide in
easily. Do not use excessive force to push
bearing in.
F. With packing flange on the shaft, continue sliding
the valve shaft toward the yoke (33) and through
the grommet (12) in the yoke (33).

the shaft so the boss on one side of the lever
shaft hole is toward the shaft bearing (8) and
engage the shaft to the lever splines.
10. Reassembly Procedures
Note: Shaft must engage lever so the indicator dot
on the clevis pin, when placed in the lever hole,
shows the valve closed. Temporarily place clevis
pin into lever (34) and check indicator dot alignment.
Dot should just start touching the closed indicator
line on the front cover (32) (Refer to figure 18). If the
orientation is not changed, align lever and mark on
yoke then check alignment. (Refer to figure 17).
