The design of the valve relies on the principle of three-dimensional eccentricity, and the spatial trajectory of the closed curve is ideal. There is no friction or inference between the sealed spaces. The whole equipment has good sealing performance, good anti-corrosion performance, good heat resistance and good wear resistance. It is small and light. Compact structure, easy disassembly and assembly, flexible operation, driven by handle, worm gear, electric, pneumatic and hydraulic. The valve is primarily used to shut off fluids and can also be designed to function to regulate and shut off fluids.
Lightweight and versatile, it is 80% to 90% lighter than traditional full body check valves.
Reduce pipe support, simplify piping, simplify installation, and reduce costs.
The spring loaded double door design has a low opening pressure.
Open 80% to ensure a positive close.
Materials and trims are available for all services within the temperature range.
Rubber metal or metal metal seats available.
