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…
Single Disc Wafer Swing Check Valve
The single disc wafer check valve adopts a short-type structural dimension and a single-disc swing design. Compared with the traditional swing check valve, this series of valves has the advantages of no external leakage, horizontal installation, good sealing performance, small linear vibration, small pressure drop, and zero seat ring wear. When installed horizontally, the valve…
Silent Check Valve EN12334
The silent check valve is mainly used in the pipelines of the water system and installed at the outlet of the water pump, and also known as a non-return valve, one-way valve, and reflux valve. It is composed of parts such as the valve body, valve disc, valve stem and spring. It has a short…
Wafer Type Check Valve
The wafer check valve, also know as wafer type non return valve, non return valve wafer type, is a type of valve that automatically opens and closes relying on the flow of the medium itself. It is mainly used to prevent the backflow of the medium, prevent the reverse rotation of the pump and its…
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…
Swing Check Valve
The swing check valve consists of valve body, bonnet cover, valve disc, and a hinge. The valve disc is disc – shaped and rotates around the hinge pin outside the valve seat passage. Its passage is designed to be streamlined, and the flow resistance is smaller than that of the straight-through lift check valve. The…
