REV LEVEL B
CAUTION
Failure to maintain proper pneumatic air line pressure could
result in damage to the valve.
Use suitable thread sealing compound only. Do not use PTFE tape.
CAUTION
The exhaust side of the solenoid should not be restricted.
This will slow the closing rate of the valve. The exhaust
module is supplied with an appropriate exhausting muffler
that ensures proper closing rate. Please consult the factory
for replacement.
IV. COMMISSIONING
After installation, connections should be tested to confirm integrity. The T4400F Systems
are equipped with a 1/4” NPT test port in the protruding end of the outlet valve shaft. See
drawing 117923. This port is directly connected to the valve's vent chamber and may be
used to confirm seal integrity on start-up and during operation.
V. DISASSEMBLY AND MAINTENANCE INSTRUCTIONS
All T4400F Systems may be completely disassembled without removal from the piping.
However, it is recommended that it be rebuilt in a shop with suitable fixturing, hoisting
equipment and tools.
NOTE:
Customers that do not feel comfortable with rebuilding and testing Skotch
valves can have them rebuilt by the factory. Call the number located on the
front cover or (800) 366-1111 and ask to speak to Skotch, Customer Service for
