Maintenancea) To Stop Steam Leakage
i) All mechanical devices require maintenance at regular intervals for continuos efficient operation. Regular scheduled
inspection of all valves is essential especially on valves which are operated only occasionally.
ii) In piston valve, the bonnet must be tightened down to prevent stem gland seal & lower Seat leakage. Applying the
recommended torque to nut will ensure any steam leaks are avoided.
iii) The piston valve is designed for either bonnet assembly replacement which includes all the necessary internal parts, or simple in-
line replacement of the upper and lower sealing rings.
iv) The valve spindle should be checked at regular interval to ensure adequate grease is present to ensure efficient valve operation.
v) When Piston valve fitted on high temperature applications or where severe weather conditions prevail, the grease should be
checked more rapidly.

b) To Replace Sealing Rings & Piston
i) Close the piston valve.
ii) Remove the bonnet nuts (12) and washers
iii) Withdraw the bonnet (7) complete with spindle (6) and piston (3).
iv) Remove the upper sealing rings (5), lantern bush (4) and lower sealing ring (2).
v) Ensure the inside surface & sealing ring's sitting surface of the valve are clean.
vi) Fit the new lower sealing ring (2), lantern bush (4) and the upper sealing ring (5).
vii) Refit the bonnet (7) complete with spindle (6) and piston (3) and tighten nuts (12) to the recommended torque.
