Loosen the wing nut then
remove the body clamp
Take apart without
scratching the gasket
sealing surfaces
Remove being careful not
to scratch sealing surfaces
Grasp the steel ball on the
top of the X-element and
remove
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
Make sure the X-element is right side up;
insert gently into the lower body
Problem
Cause
Remedy
No condensate is
discharged or
discharge is poor
(blocked)
Steam is
discharged or leaks
from the outlet
(blowing)
(steam leakage)
Steam leaks from a
place other than the
outlet
X-element is sticking to the valve seat
Valve seat is blocked
Trap operating pressure exceeds the
maximum specified pressure, or there is
insufficient pressure differential between
the trap inlet and outlet
Foreign matter has built-up of between
the X-element valve and valve seat
X-element valve and/or valve seat on the
lower body are damaged
X-element is broken
Improper installation
Clean parts
Clean valve area of the lower
body or replace lower body
Compare specifications and
actual operating conditions
Clean parts
Replace with new X-element
Correct the installation
Trap vibration
Gasket deterioration or damage
Lengthen inlet piping and fasten
securely
Replace with new gasket
Improper tightening torque was used on
wing nut
The piping has been forcibly joined using
a coupling with the incorrect bore
Tighten to the proper torque
Correct the piping
Replace with new X-element
and/or replace with new lower
body
