Series 145 VACUUM SENTRY Safety Valve – MKS

The Series 145 VACUUM SENTRY® is a patented safety valve which protects a vacuum system in the event of a power failure by isolating the vacuum system and venting the mechanical pump. This avoids oil backup and allows the motor to restart the pump easily. VACUUM SENTRY® safety valves are available with flange sizes and solenoid voltage/frequencies most commonly found on mechanical pumps
