The robust model 2680B check valve is made of stainless steel and has a spring-loaded design. It allows free flow in one direction and closes immediately if flow suddenly stops or reverses.

Reverse flow is blocked, protecting the equipment used to measure and regulate the medium. This model has female-thread to female-thread connections.

Typical applications include liquid feed lines, gas feed lines and pressurized seal-water systems where measuring equipment needs protection.
