Asahi Swing Check Valves


Check valves are used to prevent the reversal of flow in a line. When open and under flow pressure, the checking mechanism will move freely in the media, offering very little resistance and minimal pressure drop. We offer two basic types of check valves: swing check valves and ball check valves. A swing check valve utilizes a swinging disc, which requires only minimal back pressure to close the valve. This valve can also be modified, with a lever and weight or spring, to assist in seating faster to eliminate shock. The Asahi/America ball check valve employs a free moving ball, which unseats to permit flow in one direction, but seals against a seat to prevent backflow. Both types of valves may be installed vertically or horizontally.
