First, resulting in piston steam valve does not decompression or decompression failure and direct several reasons: 1, the main valve or valve sealing surface dirt, dirt can be cleaned. 2, the main valve or valve sealing surface damage, pay the seal repair or replacement grinding. 3, Lord, pay the valve spring fatigue or break, replace the new spring. 4, feedback channel C hole is blocked, clear the dirt in the channel. 5, the diaphragm fatigue or damage, replace the diaphragm. 6, piston cylinder wear or corrosion, machining correction or replacement of the piston. 7, piston ring groove and piston ring stuck, remove the piston cleaning. 8, the body cavity filled with condensate, loosen the screw to drain the condensate. Second, to solve the method is not steam 1, the valve cover installed during the cleaning misplaced, remove the bonnet positioning installed. 2, on the shims blocked plug in and out of holes, so that shim holes aligned holes. 3, into the valve access hole blocked, remove the valve cover to clear the channel dirt.
