8. Troubleshooting
If the expected performance is unachievable after installation of the steam trap, read chapter 5
again and check the following points to take appropriate corrective measures.
Problem
No condensate is
X-element is sticking to the valve seat
discharged or
Valve seat is blocked
discharge is poor
(blocked)
Trap operating pressure exceeds the
maximum specified pressure, or there is
insufficient pressure differential between
the trap inlet and outlet
Steam is

Reassembly
Tighten wing nut to the proper torque; open
inlet valve and allow live steam to enter and
heat the trap, then close the inlet valve; after
equalizing internal and atmospheric
pressures and allowing the trap surface to
cool, tighten wing nut to the proper torque
again
With the gasket in place, gently place the
upper body on the lower body
Replace with a new gasket if damaged
