CPVC UPVC Swing Check Valve

The swing check valve is based on the movement of a hinged flap or disc to control the flow of fluid through a pipe. As fluid flows forward, the valve disc, or disc, is pushed open, allowing fluid to pass through the valve. However, when flow is reversed, the valve disc or flap is forced closed by fluid pressure, preventing backflow.

This design allows the flapper check valve to automatically open and close based on the direction of fluid flow, providing a one-way flow control mechanism. The valve operates passively and requires no external power source or control, making it suitable for a variety of applications where backflow prevention is required.

What is advantage of swing check valve?

1. Strong durability: 

Swing check valve is made of high quality materials, corrosion resistance, long service life, can be applied to a variety of fluid media. 

2. Easy to open and close: 

The opening and closing of the swing check valve can be done only by rotating the handle or receiving a signal, which is simple and convenient to operate. 

3. Small fluid resistance: 

Due to the internal flatness of the valve, the resistance of the fluid through the swing check valve is very small.

4. High reliability: 

The structure of the swing check valve is simple and reliable, without leakage, and can work normally in high temperature and high pressure environment. 

5. Low operating noise: 

Swing check valves can effectively reduce the noise when opening and closing, suitable for the occasions with strict requirements on noise. 

In short, the swing check valve is widely used in many industries and fields, with durable, convenient, reliable and other characteristics.
