Solenoid Diaphragm Valves
Festo provides complete process automation solutions with a range of automated process valves, diaphragm valves, sensors and positioners.
Directly actuated solenoid valve VZWD
The valve seat is raised by the actuator alone. A closing spring holds the valve closed, with the support of the pressure of the medium. In cases of pressure loss, a normally closed function closes the valve automatically.
Force pilot operated solenoid valve VZWF
The force pilot operated valves from the VZWF series use relatively small solenoids to control high pressures with large nominal diameters. They can switch at pressures as low as 0 bar and close automatically via a normally closed function in the case of a pressure loss in the circuit.
Servo-controlled solenoid valve VZWP
Large operating pressure range for new applications: the new series VZWP extends the existing solenoid valve series VZWM. The use of a sealing piston instead of a diaphragm means that even high pressures can be controlled with a large nominal diameter. The normally closed function (normally open is not achievable with this concept) ensures that the solenoid valve closes if power is lost.
