Grooved End Check Valves

Grooved End Check Valves (equivalent to Techno Check Valve 5103) are designed for use with Victaulic® Couplings, making them fast and easy to install, remove or replace. Our Grooved End Check Valves are available in sizes up to 12" 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.

Flow Comparison MNPTFull Port Grooved End Non-Return Valves

Our Full Port, Grooved End Non-Return Valves provide more flow and lower pressure drops than conventional check valves. Grooved end valves connect easily to your piping system using Victaulic® Couplings, or equal. (Note: Male NPT version shown in illustration at right). 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.

U.S. Valve Design Conventional Design

Open flow path, low ∆P, more laminar flow Restricted flow path, high ∆P, increased turbulence

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.
