Excess Flow Check Valve

Excess Flow Check Valve :-

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. Each valve has been fabricated with a closing rate in gallons per minute and CFH/air. These valves come in a variety of different sizes and flow rates depending on their intended use. It is critical to understand what the intended service of the valve will be prior to installation.
