Quick Closing Valves

Greenwood Quick Closing Valves use a reverse check valve design to stop the flow of fluid or vapor in the event of emergency, be it fire, explosion or electrical disruption. Equipped with an external spring-assisted handle, closure is triggered by remote signal or alarm sent to electronic or pneumatic tripping devices. Fusible links which melt during a fire will allow quick closing. When resetting the valve to the normal open position, a proprietary internal relief valve breaks static pressure to help equalize pressure downstream.
