YST665Y Pneumatic Y type steam trap valve introduction
YST665Y Pneumatic Y type steam trap valve close to the linear flow design, reduce flow resistance, secondary throttling principle, reduce erosion, improve life.The YST665Y Pneumatic Y type steam trap valve core and seat adopt solid hard alloy, close inner leakage is VI class, detachable middle cavity sealing design, eliminate outer leakage, convenient maintenance and other characteristics, YST665Y Pneumatic Y type steam trap valve can be used in flammable, explosive occasions, according to the control system or adjust the signal of the instrument, cut off or open the valve, so as to achieve the use of the controlled parameters.Therefore, YST665Y Pneumatic Y type steam trap valve is widely used in remote control of thermal power plants and other industries.

YST665Y Pneumatic Y type steam trap valve is divided into positive action and reaction. Its nominal diameter grade DN (MM) ranges from 20 to 100.Nominal pressure class PN by 150lb (2.0MPa) and other grades;Air source pressure (MPa) 0.14-0.4.Signal range Pr (KPa) 20-100;40-200;The leakage is close to zero. The YST665Y Pneumatic Y type steam trap valve is available in a variety of specifications.

YST665Y Pneumatic Y type steam trap valve consists of a new series of pneumatic film actuators and y-type trap two part sets y-type trap is a special structure of the regulating body of the two ends for welding type, suitable for specific piping.The executive organ of YST665Y Pneumatic Y type steam trap valve has two forms of positive and negative functions;When the signal pressure increases, the push rod extends the positive effect of the membrane chamber, and the valve forms the air-close type.When the signal pressure increases, the push rod back into the film chamber is called reaction, and the valve to form an open type.
