Piston Actuator Power Station Valve Pn4.0mpａThree-Way Cut-Off
Pneumatic two-bit two, three-way cut-off valve, receive air pressure signal of regulation instrument, close or open valve, regulate processing parameters of pressure, temperature, flow and liquid level of system, also can receive manual given signal, achieve remote operation
This valve contain simple structure, reliable sealing, convenient maintenance and fire and explosion prevention
Structure features:
Piston actuator, small size, large output force
Sealing surface of valve spool, use soft PTFE, reliable sealing
Easy to change three-way to two-way with valve cover
Use balanced valve spool, small unbalanced force, piston actuator, enough output force
