Ball Poppet Check Valves | 4000 Series

4000 series check valves are ball-poppet type check valves used to eliminate back flow or to maintain constant back-pressure in instrument, utilility, and small process systems and equipment.  The self-cleaning ball poppet design inhibits the poppet from sticking to the valve seat for more reliable cracking and resealing.
