Description

ZS(AB)T Pneumatic Piston Diaphragm Valve

The ZS A/B/T type pneumatic piston diaphragm control valve has better stability and greater pressure difference resistance than ZJHT within a larger range of nominal diameters, while being relatively small in size and light in weight. However, it must be equipped with a valve positioner to achieve proportional regulation control. A solenoid valve can be used for two-position control. The ZS A/B/T type consists of a ZS A/B type spring-loaded piston actuator and a diaphragm control valve. It is used for the regulation and control of strong corrosive media such as strong acids and alkalis, as well as high-viscosity media with fibers, toxic and harmful media.
