The 6200 series valve uses reliable, reverse swing check valve technology to immediately stop the flow of fluid or vapor during an emergency. It stops flow quickly and remains closed providing needed isolation until primary emergency valves are reset and system safety is restored.
The valve is designed to close when a remote signal or alarm is sent to the electronic or pneumatic tripping device. Fusible links that melt during a fire also allow fast closing. Our optional valve by-pass system breaks static pressure to help equalize the pressure downstream when resetting the valve to the normal open position.
