The 3/4 in. 316 Stainless Steel Swing Check Valve (#949354) is a 316 stainless steel swing check valve that uses a hinged disc rather than a spring to allow forward flow and seal against backflow. Swing checks offer the lowest pressure drop of any check valve style, making them ideal for gravity-flow and low-differential-pressure systems.
