Check valves are specially designed for use in stainless steel pipe installations, prevent the reverse flow of fluids. Check valves are used in places at which the reflux of liquids into the pipeline must be prevented. The valves open through the pressure of the liquid against the spring-loaded valve disc. The closing process is introduced by the preloaded spring when the liquid flow into the flow direction stops. They are widely used in various processes throughout the sanitary industry, these standard non-return valves are safe and highly reliable.
