The wafer single-disc swing 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…
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…
The wafer check valve 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 driving motor, as well as the discharge of the medium in the container….
The axial flow 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 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…
The flanged check valve is the valve connected to the pipeline through flanges. It is convenient in installation and maintenance, good sealing performance, etc. Therefore, it has been widely used in industrial fields such as petroleum, chemical industry, and food industry.
Wafer Type NRV. -Wafer type non- return valve, it is a check valve, here refering to following types of wafer check valve: A wafer type NRV is usually installed between two flanges and fixed with bolts. It has a compact structure and is easy to install. It is an automatic valve that opens and closes…
