Female Thread 304 Stainless Steel Check Valve

Stainless steel check valve is mainly made of stainless steel, used to prevent backflow. It has high corrosion resistance and strength, and is suitable for various industrial environments. This kind of valve usually has a compact shape and adopts a built-in spring structure, and can be installed vertically or horizontally in the pipeline system to…

vacuum check valve

Vacuum Check Valve ANSI WCB Swing Check Valve

The vacuum check valve is mainly used in vacuum systems and needs to operate in a low-pressure or even negative-pressure environment. In terms of structural design, in order to adapt to the vacuum environment, the vacuum check valve has higher requirements for sealing performance. It usually adopts a more precise sealing structure and high-quality sealing…

How Should the Air Compressor Check Valves be Installed?

How Should the Air Compressor Check Valves be Installed?

What is the function of the air compressor check valves? The compressor check valve is a kind of one way valve that prevents the reverse flow of gas.Its main function is to prevent the gas from flowing backward after the compressor stops operating, and thus avoid causing damage to the components of the compressor so…

Swing Check Valve VS Wafer Check Valve.

In industrial product procurement, both swing check valves and wafer check valves play important roles, but there are significant differences between them. Swing check valve vs wafer check valve: main differences. Structure. Swing check valves: They have a hinged disc that swings open to allow forward flow and closes under reverse flow. They usually have…

Axial Check Valve

Axial Check Valve

The axial check valve is a specially designed valve. The opening and closing of the valve disc are operated by the pressure difference between the inlet and the outlet end of the valve. It can effectively prevent the backflow of the medium and ensure the safety of the pipeline. This design aims to solve the…
