End Connection: BW End

The tilting disc check valve features a pivot point at the center of the disc, designed to address the limitations of conventional swing check valves. Unlike swing check valves, which require higher fluid velocity and cracking pressure to remain open, the tilting disc check valve achieves full and stable opening at lower flow rates. This makes it particularly advantageous in low-pressure conditions, as it minimizes pressure drop compared to swing types. However, at higher flow rates, the tilting disc check valve experiences a slightly higher pressure drop than swing check valves.
