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…
The brass one way check valve is made of high-quality brass material, which has excellent hardness, strength, and ductility, with the size raging from 1/2″ to 4 inch. The sealing surfaces of its valve seat and valve disc are also made of copper material, and a soft-to-soft sealing method is adopted, ensuring an excellent sealing…
The vacuum swing check valve is mainly composed of a valve body, a valve cover, a valve disc and a rocker. It may also include an auxiliary spring and a weight structure to improve the sealing performance. Its internal passage is streamlined, with relatively small flow resistance, and it is suitable for large-diameter scenarios with…
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, also know as wafer 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 driving…
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…
