2.7. Check Valve
The ARGCO Check Valve is used in a DuraQuench system to prevent the reversal of
water flow. In the fully ‐ open position the clapper is held tightly against the valve
body, out of the flow stream, to provide maximum fl ow area and prevention of
clapper fl utter.
The clapper design produces quick, non ‐ slam closure before flow reversal can occur
while meeting FM requirements for anti ‐ water hammer valve rating.
Each valve is hydrostatically tested for leak tightness to 500 PSI.
