145 Vacuum Sentry® Safety Isolation Valves
Model: 145
Overview
Overview
The 145 Vacuum Sentry® 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.
