The Series 145 Vacuum Sentry® is a safety valve that protects a vacuum system upon power failure by isolating the system and venting the mechanical pump. This eliminates time consuming and costly cleanup of your vacuum lines caused by oil back streaming from the pump. The small orifice in the Vacuum Sentry also vents the mechanical pump to atmospheric pressure for easy restart when the power returns. Since it operates with atmospheric pressure and activates upon loss of electrical power, the design requires no external pressurized gas source.
Please see 145 Safety Valves on mks.com for additional configurations, literature, and product support.
