Pneumatic Piping Port - GE FVP110 Maintenance Manual

Pneumatic Piping
To connect pneumatic piping:
1. Connect the air supply pipe to the SUP port of the FVP110, and the output pressure
pipe to the OUT1 port.
Figure 32 shows the pneumatic piping ports. The port specification is chosen when
ordering the FVP110.
2. Install the Double Acting type by:
a. Connecting the output pressure pipe to the OUT2 port, ensure that the OUT2
Pressure Gauge plug does not get turned around.
b. Adjusting the pressure balance of the control relay as required (see "Tuning the
Pressure Balance of Control Relay" on page 71).
3. Check that there is no leakage from the joints.
4. Perform sufficient flushing of the piping tubes and fittings to ensure that no foreign
matter such as metal refuse can enter the piping.
The FVP110 has two air supply ports (SUP): one at the rear
CAUTION
and the other on the side. When delivered, the rear SUP
port (OUT2) is capped with a blind plug. To use the rear
SUP port, remove the blind plug and cap the side SUP port
with it. Be very careful that no foreign matter or dust caught
in the sealing tape is allowed to enter inside the pipe.
