Vacuum Isolation Safety Valve Pfeiffer Adixen ISV 25, DN 25 ISO-KF, 200 V, 50/60 Hz, 115897 / 066882
ISV Safety Isolation Valve 115897 Overview
The Pfeiffer Adixen ISV series valve is used at the inlet of rotary vane pumps (4 to 20 m3 /h) whenever isolation is required with vacuum circuit, in case of power failure. In addition, the ISV isolation valve acts as a venting valve for the rotary vane pump, while isolating the vacuum chamber. Suitable for neutral or slightly corrosive gas.
Adixen ISV Features:
- Total safety for pumping systems
- Low energy consumption
- Low dust production, thanks to slow return to atmospheric pressure
- Optional dry nitrogen gas, can be injected instead of air
- Operation in all positions
- Opens only when the inlet pressure of the pump is lower than the pressure into the vacuum chamber
Pfeiffer Adixen ISV Applications:
- Safety feature between rotary vane pumps and turbomolecular or diffusion pumps. Avoid hydrocarbon backstreaming from the rotary vane pump.
ISV Isolation Valve Operating Principle:
Start-up conditions: The different parts of the valve are at atmospheric pressure. No power is supplied to electric coil. The piston is opened under pressure from return spring.
Operating conditions: The electrical coil is powered. The solenoid valve closes, isolating the upper chamber of the valve from external air. The pumping is performed in the direction of the arrow (“pump”).
Note: on closing, a slight air flow of air (about 7 x 10-2 mbar) enters the vacuum chamber.

Pfeiffer Adixen ISV Technial Data:
- Weight: 0.640 kg
- Material: aluminium body - elastomer membrane
- Maximum working temperature: 40° C
- Leak rate: <10-4 mbar.l/s
- Air venting at closing: 7.10-2 mbar.l/s
