145 vacuum sentry vacuum safety valve

Overview

Series 225 Auto-Soft Flow Actuated Check Valves are safety valves 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 valve also vents the mechanical pump to atmospheric pressure for easy restart when the power returns. This design requires no external pressurized gas source.

NW25 - NW50
Protects vacuum system from oil back streaming in the event of power failure
Enables quick system restarts by venting the pump to atmosphere
