heavy-duty deep well check valves

US Valve’s TECHNO CHECKheavy-duty deep well check valves are a good solution to overcoming water hammer and resolving your submersible pumping systems’ check valve problems.  The TECHNO deep well checks valve’s exceptional response to quick starting pumps and exceptionally low-pressure drop distinguishes it as a superior valve for water well service.

Specially designed for deep well applications, TECHNO’s standard female threaded check valves are rated for 450 psi service or depths of 1000 ft.  Male threaded and Flanged Check Valves are also available.  Inherent features include a large free area with resulting well water valvelow-pressure loss, high integrity sealing from the continuous seal design, reduced noise and wear by the elimination of metal to metal rotating parts, and stable operation under a wider range of flow rates.

 

well water valve

          1. Full Port - Provides increased flow with reduced pressure loss
          2. Valve Plates - Offer metal-to-metal support and reduced travel
          3. Sealing Member - Provides tight shutoff and prolonged cycle life
          4. Hinge Post - Precision air foil design offers streamlined flow
          5. Spring

 

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.
