1.0 - Flow Control Valve - Model F2 - Datasheet
F2 Valve General Features
Digital Control
The Emech 2 port valve utilizes ceramic shear action
disc technology to provide tight shut-off, high pressure
differential capability and long life integrity.
The Emech 2 port valve can be fitted with the Emech digital
actuator to provide modulating control. Closed loop control can
be achieved by connection of appropriate sensors to the actuator
e.g. temperature, flow, or pressure transducers.
Combined with the Emech digital actuator, high speed stand
alone closed loop control is possible. The Emech 2 port valve
utilizes ceramic shear actions discs as the dynamic seal.

The extremely hard nature of the ceramic produces outstanding
resistance to wear and cavitation damage compared with
conventional elastomer and plastic seated valves, minimizing
seal replacement and plant downtime.

Note:
1. The charted seating and unseating torques are the sum of all friction and resistance for opening
and closing of the disc against the indicated pressure differential for normal service.
2. The relationship between values are linear, and can therefore be interpolated between nominated values.
3. The effect of dynamic torque is not considered in the table.
4. In sizing operators it is not necessary to include safety factors.
5. Break-open torques are approximately equal to the shut-off torques.
The charted values are based on clean liquid service at temperatures between 32°F to 212°F with no internal
deposition or chemical attack, operated a minimum of once a day.*
For conditions that vary from those noted above, apply the following application factors.
*Frequency of operation

2.0 Flow Control Valve - Model F2 - Installation
When installing the valve in line, be sure
to follow good practice using either
sealing tape or thread adhesive in the
joints.
The valve may be attached straight to the
pipework.
NOTE: Be sure to consider the ease of
removing the valve should this become
necessary in the future. See images 3 and
4 below for typical installation methods.
NOTE: For valve maintenance, the bonnet
screws can be removed and full access to the
internal components is possible.
The valve may be connected to the pipe
work with a union style of fitting.
The valve may be connected to the pipe
work with a thread adapter and a clamp
style fitting. e.g. Tri-Clover™.
CAUTION:
Prior to installation ensure that the pipes leading to the valve are clear from debris which may block or
damage the valve on commissioning.
WARNING:
Only trained personnel familiar with pipe work and pressure systems should install and maintain
Emech equipment. Failure to do so may result in serious personal injury!
WARNING:
Depressurize pipe work to atmospheric pressure and drain all fluids from the pipe work before working
on the valve. Failure to do so may result in serious personal injury!
WARNING:
Ensure that the intended maximum operating pressure of the line does not exceed the pressure rating
of the valve. Failure to do so may result in serious personal injury!
WARNING:
The valve must be supported adequately so as not over stress the pipe work and or the valve body.
See Figure 5 and Table 2.1 below for the maximum nozzle loads on the valves. Application of loads above
these values may result in serious personal injury and or equipment damage!

3.0 - Flow Control Valve - Model F2 - Maintenance- Dismantling
CAUTION!
Before dismantling the valve,ensure all
upstream and downstream pressurised pipe
work is isolated appropriately.
Ensure the pressure and fluids are drained
from the valve and pipe work.
After removing the gland nut locking screw,
unwind the gland nut counterclockwise using
the spanner provided. (Image 1)
Using a hex wrench, remove the four cap
screws around the bonnet. (Image 2)
Carefully remove the bonnet from the body
particularly if the valve is mounted in a
vertical position.
The spindle may detach from the rotating
disc and remain in the bonnet.(Image 3).
Remove the spindle and ensure that the two
thrust washers and needle bearing is on the
spindle. You may have to remove these from
the bonnet.
Alternately the spindle may stay attached to
the rotating disc in which case it should be
carefully removed. (Image 4)
In either situation, the spindle will need
to have two O-rings and two wear rings
removed (Image 5).
Remove the discs from the valve body.
Remove two energizers and check the pins
for any damage. If the pins are damaged
they need to be ordered separately (Image
7).
Finally remove the O-ring around the flange
of the bonnet (Image 8).

4.0 - Flow Control Valve - Model F2 - Maintenance - Reassembly
Replace the pins if they are damaged.
Before assembling/re-assembling the valve,
make sure hands are free of dirt and grease
and the valve is clean.
Fit the energizers into the body. Apply a light
even coast of grease to all seals. All Emech
seal kits are provided with recommended
lubricant. (See table 4.2 on page 15).
Place the bottom disc onto the valve body.
Apply a light even coat of grease to the top
surface of the bottom disc. (Image 3)
Place the top disc on the bottom disc and bed
it down by rotating one on the other.
Ensuring the disc slots are clear of dust or
dirt, check the spindle fits neatly into the slots
on the top disc.
NOTE: The spindle should be tight fitting. If
the spindle does not sit flat on top of the disc,
clean lugs. If the spindle still does not sit flat,
file the lugs.
Fit the two O-rings and d the top and bottom
wear rings to the spindle.

4.0 - Flow Control Valve - Model F2 - Maintenance - Reassembly
Apply a light even coat of grease to the
spindle bearing surfaces and the O-rings
(Image 7).
Check the fit of the spindle in the bonnet
(Image 8). If the spindle fits, proceed to
Image 9.
Lightly grease both sides of the thrust washer
and place on the spindle. Place on the
needle roller bearing (Image 9) and apply
grease (approx 60% of the void space).
Lightly grease both sides of the second thrust
washer and place on the bearing.
Apply a light even coat of grease to the body/
bonnet seal O-ring and bonnet bore. Place
the O-ring around the perimeter of the bonnet
(Image 1).
Align the discs with the spindle on top before
gently lowering the bonnet over the spindle
down to the body (Image 11).
Secure down the bonnet with the allen head
cap screws using an allen wrench (Image
12).
Check the torque of the bolts to the range
indicated in table 4.1. (See table 4.2 page
15).
Rotate the spindle one full rotation. The
movement should be smooth and even with
no variation in torque (Image 13).
Lubricate inside and outside of the gland
nut, paying particular attention to the thread.
Insert the O-ring in the gland nut and then the
external O-ring (Image 114).

With the gland wench provided, screw
the gland nut down until it bottoms out.
Do not over-tighten! (Image 15).

Back the gland nut off 3 notches (70
degrees). If the notch does not align with the
locking screw head, back the gland nut off
further to align (Image 16).

“Zero”
Notch
Insert the locking screw after applying a thread locking adhesive (Image 17). Tighten the
locking screw as per the torque values given in table 4.1.
NOTE: Rotate the spindle 1-2 times to ensure the operating torque is constant, and the
rotating action is smooth.
Reassemble and connect the handle kit or actuator to the valve. When connecting to
an actuator, ensure that the valve and actuator are both in the “zero” or starting position
