ACEV Flow Control crafts an exceptional range of check valves, adhering strictly to API, ASME, and ANSI standards during manufacturing and testing.

Our Piston Check Valves, also known as Lift Check Valves, operate silently while effectively mitigating backflow. Their innovative "flapperless" design ensures gentle interaction with the seat as the piston moves with fluid flow variations.

Forged steel check valves, including Piston Check Valves, are vital for preventing reverse flow in pipelines. As fluid pressure builds, the valve opens, and any flow reversal triggers its closure. In Piston Check Valves, a body-guided disc glides within the bore, ensuring precise seat and disc alignment during closure. Installed with flow beneath the disc, inlet pressure and flow force the disc to "lift," facilitating fluid passage. If flow reverses, the disc swiftly descends, assisted by its weight, to prevent fluid from returning. However, caution is advised when using these valves in dirty media, as debris may cause the disc to stick within the bore.

The piston, or lift, check valve utilizes a piston as its valve disc to regulate fluid flow. Prior to exploring its functionality, it is essential to examine its components through a typical diagram.

ACEV's piston check valves are compact forged steel valves suitable for both horizontal and vertical lines. Notably, the pressure seal piston check valve boasts a robust yet compact design, ideal for high-pressure and high-temperature applications.
