Product Introduction
The H74 ultra-thin wafer check valve is a fluid control device designed for installation in space-constrained environments, primarily used in urban water supply systems, petrochemical and metallurgical industries. Its compact design, thin valve body, and light weight solve the problem of difficult installation of traditional check valves in confined spaces.
The valve consists of a valve body, valve disc, and sealing components, preventing backflow of the medium through a one-way opening and closing mechanism. The main body material can be carbon steel, stainless steel and the sealing ring is made of composite materials such as nitrile rubber and Viton, supporting horizontal or vertical installation.
