XPro Series
Procedure
Over time components of the Trifecta XPro Series (as in any
mechanical system) can degrade and/or fail if not properly
is recommended to prevent any unexpected downtime.
•
completely removed by service technician permitting
entry of debris to system.
• Malfunctioning solenoids and check valves (leaks) caused
by:
– Buildup of impurities of liquid fed to the system from
the bulk tank
– Introduction of moisture to the bulk system without
proper purge process
–
due to cycling
– Debris entering Trifecta XPro Series from bulk station
due to removed strainer
•
– All connections are leak checked from the factory and
should be re-checked periodically
–
ensure proper operation
• Malfunctioning cylinder reliefs
– Relief valve opening at lower pressure than set point
– Burst disc rupture (fatigue failure)
failures and corresponding down times can be prevented. To
following maintenance procedures be followed:
• Every six months:
– Clean/replace strainer on liquid feed line
Note:
strainer in place.
Preventive Maintenance
• Every year:
– Verify two normal operation cycles.
– Inspect integrity of all wire connections in control
box. Tighten all loose connectors.
– Verify accuracy of analog gauges against pressure
transmitters and DP transmitters.
– Leak check entire Trifecta XPro Series system.
–
•
per tank)
– Replace all check valves
– Replace pistons on all solenoid valves and rebuild
cryogenic ball valves
– Replace relief valves and burst discs on tanks 1 and 2

counter in the PLC. Note cycle count if
torqued to 10 to 12 foot-pounds of torque in a normal cross
valve to stick open or closed. It is also recommended that
bolts are tightened and will not re-seal a second time.
When the pneumatically actuated ball valves that are on the
be taken to insure that the relief port in the ball is oriented so
it vents on the upstream side of the valve. Failure to properly
orient the vent port in the ball will cause the valve to leak by.
