ZDT8 type pneumatic diaphragm single seat regulating valve

ZDT8 type pneumatic diaphragm single-seat regulating valve, single-seat plunger-shaped spool, spool with top-bottom guide. It is used for occasions with strict requirements on leakage, low pressure difference before and after the valve, certain viscosity and fibrous medium. For high pressure difference and large diameter valve, it should be used in conjunction with positioner
