Function and Characters

This valve is mainly used for connection and interruption for the media such as water, oil and others in the pipeline. And the main function of this valve is to stop the medium from back off and bleeding from the container.

The face to face of this valve is short, as well as with a small volume and light weight.

The disc can be closed quickly.

It can be used in both horizontal and vertical piping, which is also convenient for installation.

With a small fluid resistance, the valve is unimpeded.

It is flexible, with good sealing.

The structure is simple and compact, and the appearance is beautiful.

The service life is long with high reliability.

Double Disc Check Valve: A double disc check valve has two discs, one on each side of a central hinge or shaft. The discs are designed to open and close simultaneously in response to the flow direction, ensuring effective sealing against backflow.

Double Disc Check Valve: Double disc check valves offer enhanced sealing and reduced pressure drop compared to single disc check valves. The two discs work together to provide symmetrical closure, improving sealing efficiency and minimizing the chance of leakage.

Double Disc Check Valve: Double disc check valves are designed for more demanding applications, including high-pressure systems or systems with higher flow velocities. The symmetrical closure of the discs helps ensure a tight seal, reducing the potential for leakage.

Double Disc Check Valve: Double disc check valves are primarily designed for horizontal installations. While they can also function in vertical positions, their performance may be compromised, and additional measures might be needed to ensure proper closure.

Double Disc Check Valve: Double disc check valves are generally available in larger sizes to accommodate higher flow rates and larger pipe diameters. They are often used in industrial settings and applications with higher flow demands.
