Forged Swing Check Valve

Swing check valve, also known as reverse stop (flow) valve, is used for one-way flow pipeline to prevent the backflow of the medium on the automatic valve.

According to the pressure in charge of the flow of the road medium to open or close the valve itself, it can be divided into single-valve, double-valve and multi-valve type three, belong to one of the more commonly used valves.

Swing check valve is generally applicable to the fluid medium more clean pipeline, which does not suitable for large viscosity or containing solid particles of the working conditions. Otherwise, it will lead to the check valve opening is not sensitive, as well as can not achieve a complete seal. 

Swing check valves only allow the medium to flow in one direction, which can effectively prevent the medium from backflowing to prevent accidents.

Key Features:

1. Swinging Disc Design:

   • The valve uses a disc that swings open on a hinge or pivot when fluid flows in the correct direction.

   • When flow stops or reverses, the disc swings back to its closed position, preventing backflow.

2. Low Pressure Drop:

   • When fully open, the disc moves out of the flow path, minimizing pressure drop and turbulence.

3. Simple and Reliable Operation:

   • The swinging disc design is straightforward, with no springs or complex mechanisms, making it reliable and easy to maintain.

4. Durable Construction:

   • Constructed from materials such as stainless steel or carbon steel, swing check valves are designed to withstand high pressures, temperatures, and corrosive environments.

5. Suitable for Horizontal and Vertical Installation:

   • Swing check valves can be installed in both horizontal and vertical pipelines, provided the disc can swing freely to close.
