Isolation Channel
Actuator Testing
– Fluid Section Fitted:
Follow the steps listed for testing the actuator with the fluid section removed, but when
testing for air leaks at the Bottom Bush (6983), apply soapy water to the Isolation Channel
shown in the image below.
Fluid Section Testing
– Vacuum Integrity:
1. Ensure the Resin inlet and Purge outlet hoses are exhausted and not connected to
any equipment.
2. Insert the Lower Valve Body (6986) nose into the universal insert on the top of the
IVX3 Service Module.
3. Connect the Inject output on the top of the Service Module to the Inject signal port
on the IVX3.
4. Connect the Purge output on the top of the Service Module to the Purge signal port
on the IVX3.
5. Ensure the valve is not actuated (no air supplied to either pilot) and the valve is in
the closed position.
6. Open the isolation valve on the Service Module and then adjust the vacuum level
at the universal insert to the maximum level (80% + vacuum). If this level cannot
be reached, do the following:
a. Check the test equipment by plugging the universal insert and ensuring a
high vacuum can be achieved.
b. Check the two O-rings (3265) on the IVX3 are in good condition.
If this is not the problem, the valve seal is leaking an unacceptable amount and the
valve fluid section should be serviced.
