The Vacuum Sentry 145-0040K-208V/60 Safety Valve has a KF40 port size, Angle ports, Viton seals, and a solenoid voltage of 208VAC. 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. It 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.
