Tulsa’s threaded swing check valves are high-quality check valves assembled and tested in Houston, Texas. Our swing check valves are available in ductile iron or carbon steel. All of our threaded swing check valves conform to NACE MR0175 requirements to meet your corrosive service needs. The clapper and seat design are beveled and self-aligned to ensure zero leakage. The molded clapper seal design ensures a seal at one (1) PSI differential. Our design provides a full bore opening to ensure a very low-pressure drop. Tulsa Valve performs 100% pressure testing to API 598 standards on all of our swing check valves.
