Single plate wafer check valve
Valvesonly Europe is one of the most well known single plate wafer check valve supplier and manufacturer and also a significant provider of high-quality goods, and the secret to our success in the valves industry is our well-integrated work environment.

Wafer check valve, single disc check valve, or swing check valve are all terms used to describe a single plate wafer check valve. In pipeline installation, a single plate check valve is used to prevent back flow. According to DIN, JIS, or ANSI specifications, they are designed to be placed directly between flanges. This valve is appropriate for use in pipeline installations for the transportation of liquids and gaseous fluids in the industrial sector. Fluids on one side of the pipe would be blocked within acceptable temperature and working pressure limitations. They are not suited for use in solid-particle media. ​

The valve features a solid body with a thin plate profile in the centre that allows it to be installed between flanges. Flanges are used to connect pipes, valves, and other piping equipment in order to create a pipeline system.

The flange connection screws keep the single plate check valve in a central position. The number of screws required for each installation is determined by the size of the valve. The valves are protected from external influences by an O-ring seal. Under low pressure, a single plate check valve functions. The valve facilitates cleaning and maintenance very quickly.
