Female NPT Check Valves
Female NPT Non-return Valves are available in sizes up to 3" in Carbon Steel (Zinc Dichromate plated for added corrosion resistance), 316 Stainless Steel, Brass and Aluminum. Available elastomers include Buna N, EPDM, Viton, Silicon and Teflon. Valve internal components can be customized to fit your exact application requirements.
Full Port Female NPT Check Valves
Our Full Port, Female NPT (FNPT) Check Valves provide more flow and lower pressure drops than conventional check valves. Our elastomer hinge check valve design takes performance to an entirely new level by eliminating the restrictive valve seat and substantially increasing the valve’s open area and flow coefficient (Cv). They are ideal for application in vacuum pumps, compressed air and gas systems as well as in water systems where low head loss and elimination of water hammer are desirable.
Fast Delivery
We maintain an extensive inventory of valves, parts and components in a wide variety of materials so we can respond to your needs quickly. Valves are typically assembled and tested within 1 to 2 days after receipt of an order.
