Overview

Pneumatic thin film explosion-proof regulating valve, Tingyang brand ZJHP (M) type pneumatic single seat (sleeve) regulating valve, consists of a pneumatic multi spring thin film actuator and a low flow resistance straight through single seat valve (sleeve valve). The single seat valve body is directly connected to the single seat cover with a guiding structure, and the valve core is a plunger type structure. Compared with ordinary single seat valves, it has the characteristics of small volume, light weight, and high flow rate, and is suitable for occasions with high flow rate and strict leakage requirements.

Product Details

1Pneumatic thin film explosion-proof regulating valveProduct Information:

Product Model: ZJHP (M)
Product Name: Compact Pneumatic Thin Film Single Seat (Sleeve) Regulating Valve,Pneumatic thin film explosion-proof regulating valve
Product features: The Shangming brand ZJHP (M) pneumatic single seat (sleeve) regulating valve consists of a pneumatic multi spring thin film actuator and a low flow resistance through single seat valve (sleeve valve). The single seat valve body is directly connected to the single seat cover with a guide structure, and the valve core is a plunger type structure. Compared with ordinary single seat valves, it has the characteristics of small volume, light weight, and high flow rate, and is suitable for occasions with high flow rate and strict leakage requirements. Compared with ordinary sleeve valves, the ZJHM type precision small sleeve valve has the characteristics of 1/3 smaller volume, 1/3 lighter weight, and 1/3 larger flow rate. It is widely used in industrial process automatic control systems that require low noise and large pressure difference.
