Rubber Flap Check Valve is designed to prevent reverse flow automatically. During system flow conditions,the movement of the fluid forces the valve disc to the open position allowing 100% UN - restricted flow area through the valve,Under reverse flow conditions,the disc automatically returns to the closed position to prevent reverse flow. The valve is of the swing check type utilizing an angled seat and fully encapsulated, resilient disc.
