III. INSTALLATION
A. Unpacking
Do not remove protective plastic plugs until ready to install.
Verify no debris or foreign objects are inside the valve.
Transporting - use proper hoisting procedures to avoid damage to valve. If using a
sling, it should be placed on the body, not the actuator cylinder.
CAUTION
Note: Valve weighs over 265 lbs in base form. Use proper
lifting safety precautions for transporting the valve.
Purge the fuel line prior to installing the valve.
Purge all pneumatic air lines prior to connecting solenoids.
CAUTION
Note: Do not lift or pull on the electrical conduit lines Doing
so may cause the POC switches to come out of calibration.
Historically many problems at start-up are due to mishandling of the valve
and poor purging of the fuel lines and pneumatic control lines.
B.
Valve Installation
WARNING
Prior to installation and/or start-up, piping should be
verified as being free of dirt, grit, welding slag, or other
particulate contamination. Failure to do so may result in
damage to valve internals.
