Product Description

Waits Valve high quality Bronze Swing Check Valve is a valve that relies on the flow of the medium to open and close. This valve disc rotates around the pin shaft to open and close automatically when there is no reverse pressure. It has a simple structure, small flow resistance, and smooth opening and closing. Bronze Swing Check Valve: This product has a compact and reasonable structure, reliable sealing, stable performance, and has the characteristics of small size, light weight, and a wide range of applications. It is suitable for seawater, fresh water, sewage and some weakly corrosive chemical media where corrosion resistance is required.

Product Advantages
1.It adopts an internal rocker arm swing structure, with all the opening and closing components installed inside the valve body. It does not penetrate the valve body. Except for the middle flange part which uses a sealing gasket and sealing ring, there are no external leakage points in the whole structure, which can prevent external leakage of the valve. The connection between the rocker arm and the valve disc adopts a spherical connection structure, allowing the valve disc to have a certain degree of freedom within 360 degrees.
2.The sealing surfaces of the sealing pair can be welded onto the body or hard alloy. Even in the presence of fine particles in the medium, it is not easy to be worn out quickly due to erosion, ensuring good sealing performance.
3.When opening, the valve disc can quickly rotate to the fully open position. The fluid passage is almost unobstructed, the flow channel is smooth, and the fluid resistance is small.
4.It is suitable for various media, such as clean water, steam, oil products, etc., and can also be used for some weakly corrosive media. The applicable nominal pressure and temperature range are relatively wide, meeting the needs of various working conditions.
5.The installation position is not restricted. It can be installed on horizontal, vertical or inclined pipelines. For example, when installed on a vertical pipeline, the medium flow direction is from bottom to top.
