Safety Valve, Pump Failure, NW25 ISO-KF, Viton, 24 VDC

The patented 145-0025K-24VDC Vacuum Sentry® Safety Valve has ISO-KF flanges, NW25 port size, Angle ports, Viton seals, and a solenoid voltage of 24VDC. It protects a vacuum system in the event of a power failure by isolating the vacuum system and venting the mechanical pump. 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.
