Water Treatment Check Valves
U.S. Valve's check valves and full port ball valves are used extensively on low pressure aeration blowers and fans and can be used for any application where less pressure drop or a reduction in head loss is desirable. ANSI Dual Plate Wafer Check Valves, designed to API 594 and tested to API 598, are also available and can most often be shipped from stock.
Full Port, Lowest Pressure Drop
Full Port 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). Our Full Port Ball Valves offer open flow paths, thus reducing turbulence and noise. 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.
NSF Certified Check Valves
U.S. Valve’s check valves are certified to meet the requirement of NSF 61 and NSF 371. Our valves are safe to be used in water treatment and purification, distribution systems, potable water, and much more. Proudly offering NSF-certified “lead-free” valves, you can safely use several of our valves in your water and wastewater treatment facilities.
