Product Description
The Festo VZWP is a force pilot-operated 2/2-way solenoid valve featuring a unique piston seal instead of a conventional diaphragm, enabling the control of high pressures and high flow rates using relatively small solenoids. Ideal for controlling gaseous and liquid media in open circuits, this robust brass valve reliably switches water, air, and neutral fluids at differential pressures from 0.5 bar up to 40 bar.
Key Features & Advantages:
Unique Piston Seal for High Pressure: Utilizes a sealing piston instead of a diaphragm, allowing even PN40 high pressures to be controlled with large nominal diameters. The valve closes automatically in the event of power loss.
Reliable Servo-Controlled (Force Pilot) Operation: Requires a minimum differential pressure of only 0.5 bar to operate (max 40 bar). This makes it specifically suitable for applications where pressure is present between the input and output of the valve, including systems exhausting into open air.
High Flow Rate with Small Solenoid: Despite its robust metal housing, the valve achieves very high flow rates (e.g., 12,250 l/min) while maintaining compact dimensions. This efficient design utilizes the medium pressure for support.
Versatile Material & Connection Options: Manufactured with a durable cast brass (CW617N) housing (CRC 1 – Low corrosion stress) and FPM seals. Available in G-thread (G1/2, G3/4, G1) and NPT thread sizes, ensuring compatibility with international piping standards.
Simple In-Line Installation & Soft Sealing: Features a soft sealing principle, easy in-line pipe installation, and a coil mount position preferably on top to ensure long service life and reliable shut-off.
