Check valve refers to the valve that automatically opens and closes the disc depending on the flow of the medium itself to prevent medium backflow, also known as check valve, one-way valve, counterflow valve, or back pressure valve. Check valve is an automatic valve. Its main function is to prevent medium backflow, reverse pump and drive motor, and release of container medium. Check valves can be divided into swing check valves (rotating according to the center of gravity) and lift check valves (moving along the axis). By choosing different structural forms and materials, it can be widely used in water, steam, oil, acid, alkali and other media.
Product characteristics
The clamp lift check valve has short structure length, small volume and light weight. It brings great convenience for valve installation, handling, storage and pipeline layout, and can save a lot of materials and reduce engineering cost.
The valve is integral structure, simple and compact, and can be installed horizontally or vertically.
Disc travel is short, impact force is small when valve closes, and spring assisted closure, closing speed is fast.
Large fluid resistance, small water hammer pressure, long service life and high reliability.
