Enhance system safety by preventing uncontrolled release of system media if downstream line ruptures with excess flow valves.

Excess Flow valves are known by other names such as velocity check, emergency shutdown device, seismic valve, shutdown valve, surge preventer, earthquake valve, and line rupture valve. These …

F Series excess flow valves are intended to close upon excessive discharge of vapor or liquid resulting from a break in the hose or piping system. They are used to protect cylinder, tank and piping …

WHAT IS AN EXCESS FLOW VALVE? Excess Flow Check Valves are spring-actuated safety devices that shut off the flow of fluid in case any flow line or fitting located on the outlet side of the valve …

Sep 16, 2022 · An excess flow valve is a mechanical safety device used primarily on gas or liquid distribution lines to reduce the risk of accidents. When activated, either by a significant pressure drop …

This mechanism involves a valve that shuts off the gas supply, blocking further flow. These are usually spring-loaded flow shut-off valves. When the flow through the valve exceeds a previously set closing …

The Fainger make Excess flow check valves are used for installation in liquid/gas lines flowing into and out of pressure tanks. Their main function is to stop excessive flow of the tank contents liquid/gases …

An excess flow valve is a spring loaded check valve which will close only when the flow of liquid or vapor through the valve generates sufficient flow or force to overcome the power of the spring holding it open.

Valcor’s V520-50 Excess Check Valves provide protection against a surge flow in a process line caused by a downstream line rupture or component failure. Excess Flow Check Valves quickly and safely …

Excess Flow valves are in-line valves through which pressurized gas or liquid flows in either direction. These are spring-loaded flow shut-off valves, which will only close when the flow through the valve …
