  • Product description: ZJHP Pneumatic diaphragm flow control valve
ZJHP Small pneumatic membrane single-seat control valve is composed  of new multi-spring pneumatic membrane actuator and top-oriented straight through low-flow single seat valve. Equipped with electric-pneumatic valve positioning or pneumatic valve positioner, with electrical signals and compressed air as the driving force to accept the control system input 0-10mA DC or 4-20mA DC current signal, the regulator will transfer compressed air into air pressure signal to input or output, can achieve split control(segment signal), thus changing the valve opening displacement to precise control and asjust the fluid medium process parameters. Small pneumatic diaphragm control valve has advantages of compact structure, light weight, sensitive action, fluid channel was S streamlined, small pressure drop loss, large valve capacity, flow characteristics is precision, easy disassembly and so on. Controlling is simple, response fast, no need to take another explosion-proof measures.
