    Compact Flange-Mount Check Valves

    Less than half the end-to-end length of standard flange-mount check valves, these can be installed between ANSI flanges in pipelines with limited clearance. ANSI flanges are sold separately. Valves open to allow flow in one direction and close when flow stops or reverses. All have a 316 stainless steel body for excellent corrosion resistance.
