Force Pilot Operated Solenoid Valve VZWFSource: Festo Corporation
The force pilot operated valves from the VZWF series can be operated without differential pressure, e.g. can be used in closed media circuits.
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.
The advantages at a glance
• Can be operated with water, air and neutral media
• Possible to control high pressures with large nominal diameters
• Generally suitable for use in all cases where the medium can be vented downstream of the valve into the atmosphere or into a tank
• Operates from 0 bar
• Ideal for applications in closed media circuits
• Integrated N/C function
