Safety Valve, Pump Failure, NW25 ISO-KF, Viton, 120 VAC 60 Hz
The 145-0025K-120V/60 Vacuum Sentry® Safety Valve has ISO-KF flanges, NW25, Angle ports, Viton seals, and a solenoid voltage of 120VAC. It is a patented safety valve that protects a vacuum system in the event of a power failure by isolating the vacuum system and venting the mechanical pump. The Vacuum Sentry protects vacuum systems from oil backstreaming via the pump. A small orifice vents the mechanical pump slowly to atmospheric pressure for easy restart when power returns.
