Pfeiffer Adixen ISV 25 Vacuum Isolation Safety Valve, DN 25 ISO-KF, 220 V, 50/60 Hz, 115898 / 066832
Pfeiffer ISV 25 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
ISV 25 / 115898 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.
ISV25 Applications:
- Safety feature between rotary vane pumps and turbomolecular or diffusion pumps. Avoid hydrocarbon backstreaming from the rotary vane pump.
