ZMQS Y Type Pneumatic Steam Trap is constructed with a new series Pneumatic Diaphgram Type Actuator and a Y Type Steam Trap. Y Type Steam Trap worked as a control valve with a special structure. Both ends of this Pneumatic Steam Trap are Welded Type, which is suitable for specific pipe matching.

This Pneumatic Actuator has Positive and negative functional styles. When the signal pressure increased, the push bar extruding the diaphragm chamber, this is called positive action, which combined with the steam trap to constitute Air Closing Style. When signal pressure increased, push rod returning back to the Diaphragm Chamber, this is called negative action, which combined with valve to constitute air opening style.

ZMQS Y Type Pneumatic Steam Trap working principle:

The signal pressure which was input into the diaphragm chamber can push the diaphragm to compressed the spring in the diaphragm actuator, then the valve stem will move accordingly to change the circulating area between the valve disc and valve seat until the counter force of spring is equal to signal pressure action, so as to realize the target of automatically adjusting technical parameter.

ZMQSY/ZDLSY Series of Pneumatic/Electric "Y" Type Trap Valve are according to thermal power plant equipments to drain, which is professional developing, designing and manufacturing to be a new generation steam trap. It is nearly linear flow design, to reduce flow resistance; It has twice throttle principle to reduce erosion and improve life. Plug and seat use whole hard alloy, its shut-off leakage≤ VI; Seat is compaction structure, it could be designed into move mid-cavity sealing, with advantages of preventing leakage, convenient maintenance etc, it also can be used in flammable and explosive occasions. According to the signal of control systems or instrument to shut-off or open the valve, so it could be meeting the requirements of controlled parameters. And it is widely used in the remote control of the power plant industry
