Type 119 Control Valve
Introduction
Scope of the Manual
This instruction manual provides installation, spring
adjustment, maintenance, and parts information for
the Type 119 control valve.
Description
The Type 119 control valve (Figure 1) is used for
on-off or throttling control of noncorrosive or mildly
corrosive liquids and gases. It is designed to meet the
low-pressure liquid and gas application requirements
in many varied industries.
As loading pressure is applied to the Type 119 control
valve diaphragm, the disk holder is pulled off the
orifice. As loading pressure is reduced, the opposing
spring force moves the disk holder toward the closed
position, resulting in spring-close action should a loss
of supply pressure occur.

Specifications
The Specifications table lists the specifications for the
Type 119 control valve. Some of the specifications for
a given control valve as it originally comes from the
factory are stamped on a nameplate (Figure 2) located
on the spring case flange.
Installation
!
Warning
1. Before installing the valve, be sure the valve body
and associated equipment are free of damage and
foreign material.
2. The control valve can be installed in any position,
but the normal orientation is with the actuator
D100261X012
To avoid personal injury or property
damage caused by controlled process
fluid or bursting of pressure-retaining
parts, be certain the service conditions
do not exceed the limits shown in
Specifications section. The leak-off and
spring case vents must be kept open.
To avoid danger of fire or explosion
from venting of flammable or otherwise
hazardous fluid into a closed or poorly
vented location, pipe the vents to a
well-ventilated location, away from any
buildings or windows so as not to create
a further hazard.

Type 119
Spring Adjustment
Maintenance
The control valve spring has been selected to meet
the pressure condition requirements of the application
as specified on the order. This pressure condition is
stamped on the actuator nameplate.
Valve parts are subject to normal wear and must be
inspected and replaced as necessary. Inspection
and maintenance depends on the severity of the
service conditions.
The spring has a fixed pressure span over which
loading pressure will stroke the valve. Adjustment of
the spring compression shifts the span so that more
or less loading pressure is required to start travel.
Since the span does not change, there will be a
corresponding increase or decrease in the pressure
requirements at the end of the valve stroke.
If the control valve has been disassembled or pressure
conditions have changed, the spring may need
adjustment to make the valve travel coincide with the
diaphragm pressure range. Make the adjustment in
the following manner. Key numbers refer to Figure 3.
1. Loosen the locknut (key 13) on the spring case.
2. Turn the adjusting screw (key 12) clockwise to
compress the spring (key 16) or counterclockwise to
decrease spring compression. Increased spring
compression results in increased loading pressure
necessary to start travel. Decreased spring
compression results in less loading pressure required
to start travel.
3. After adjustment, tighten the locknut. Note that
the spring can be identified by the color code.
Depending on how much conditions are changed,
it may be necessary to install a new spring, using
appropriate steps in the Maintenance section. After
changing the spring, adjust the valve using the above
steps in this section, and indicate the new spring
range on the nameplate.
!
Warning
To avoid personal injury or property
damage caused by sudden release
of pressure or uncontrolled process
fluid, isolate the control valve from the
pressure system, and release all pressure
from the valve body and actuator before
performing maintenance operations.
The following describes the procedure for complete
disassembly and assembly of the actuator-valve body
combination. When inspection or repairs are required,
disassemble only those parts necessary to accomplish
the job. Key numbers refer to Figure 3.
Disassembly
1. Isolate the control valve from all pressure, and
release pressure from the valve body and actuator.
Loosen the locknut (key 13), and remove all spring
compression from the control valve by turning the
adjusting screw (key 12) out of the spring case.
2. Remove the two bonnet cap screws (key 15, not
shown) that secure the bonnet to the body, and lift
the spring case, bonnet, and trim assembly from
the body.
3. Examine the seating edge of the orifice (key 3). If it is
nicked or rough, unscrew it from the body with a thin
wall 7/8-inch (22 mm) socket wrench, and replace
it with a new seat ring of the proper size.
4. Remove the bonnet O-ring (key 11), and inspect it
for wear damage.

Type 119
5. Unscrew and remove the spring case cap screws
(key 14). Remove the spring case, upper spring
seat, and spring (keys 2, 17, and 16). Do not
lose the nameplate (key 20) when removing the
spring case.
6. Pull the hairpin clip (key 6) from the stem and
remove the disk holder assembly (key 4).
7. Pull the diaphragm/stem assembly (key 5) out of
the bonnet (key 9), and inspect for damage or
deterioration. If necessary, replace the entire
diaphragm assembly.
8. Without removing the O-rings and bushing spacers
(keys 8 and 7) inspect their inside diameter
surfaces for damage or deterioration.
Note
The following step should be performed
only when there is an indication of O-ring
or bushing spacer failure.
(key 22) or equivalent, and install as shown in
Figure 3.
3. Carefully slide the diaphragm assembly (key 5) into
and through the O-rings and bushing cavity. Turn the
diaphragm assembly to line up the diaphragm holes
with the bonnet holes.
4. Slide the disk holder assembly (key 4) all the way
into the stem. Connect the disk holder assembly with
the hairpin clip (key 6).
5. Coat the bonnet O-ring (key 11) with Dow Corning
No. 111 lubricant (key 22) or equivalent. Install the
O-ring in the recessed notch in the bonnet (key 9).
6. Mount the bonnet (key 9) on the valve body (key 1),
insert two cap screws (key 15, not shown), and
tighten to 7 foot-pounds (9,5 N•m).
7. Put the spring (key 16) on the diaphragm assembly
(key 5), and place the upper spring seat (key 17) in
the end of the spring.
9. Remove the internal retaining rings, stem wipers,
O-rings, and bushing spacers (keys 10, 19, 8 and 7).
Inspect these parts for wear or deterioration,
and replace if necessary.
8. Lubricate the point and threads of the adjusting
screw (key 12) with Never-Seez(1) lubricant (key 21)
or equivalent.
Assembly
9. Position the spring case (key 2) and nameplate
(key 20) on the diaphragm assembly (key 5). Insert
the cap screws (key 14).
This procedure assumes that the control valve has
been completely disassembled. If the control valve
has been only partially disassembled, start these
instructions at the appropriate step.
10. Tighten all cap screws until finger tight. Then,
following a crisscross pattern, tighten each
cap screw.
1. If the orifice (key 3) was removed during disassembly,
lubricate the threads with Never-Seez(1) lubricant
(key 21) or equivalent, and screw it into the valve body
using a thin wall 7/8-inch (22 mm) socket wrench.
11. Connect the control piping to the control connection
in the bonnet.
2. Lubricate the bushing spacers, O-rings, stem wipers,
and internal retaining rings (keys 7, 8, 19, and 10)
with Dow Corning(2) No.111 silicon-base lubricant
12. Adjust the spring by following the procedures in the
Spring Adjustment section, and remark the
nameplate if necessary.
