The new VZWP series of servo-controlled solenoid valves available from Festo extends the existing VZWM series for greater versatility in application.
Offering a large operating pressure range for new applications, the new VZWP solenoid valves make use of a sealing piston instead of a diaphragm to allow even high pressures to be controlled with a large nominal diameter. The normally closed function ensures that the solenoid valve closes if power is lost.
Suitable for virtually unlimited use, VZWP valves can be operated with water, air and neutral media wherever there is a pressure difference between the valve input and output. This includes applications where the medium is expelled into the open air or flows into an unpressurised container downstream of the valve. The new valve series is not suitable for closed circuits.
VZWP solenoid valves are ideal for wide-ranging applications from production automation to process automation. The series includes brass valves with a choice of nitrile rubber and fluoro elastomer seals, enabling the valve to be tailored to the respective application. Choice of G and NPT thread for the pipe connection is also offered.
VZWP solenoid valves are ideal for controlling gaseous and liquid material flows in production and process automation applications with:
- Differential pressure of at least 0.5 bar
- Open medium circuit
- Media with viscosity up to 22mm²/s
