Check valve Model 2680B has a robust spring-loaded stainless steel construction which allows free flow of a medium in one direction, but which closes immediately upon flow ceasing or changing direction. Reverse flow is prevented thereby protecting any measuring or regulating equipment from process media. This model has female-to-female connections. Typical applications are where the protection of measuring equipment is required, liquid feed lines, gas feed lines and pressurized sealing liquid water systems.
