Forged Ball Check Valve

Forged Ball Check Valve

Forged-steel-Y-Ball-Check-Valve
Ball check valves are generally used to protect pumps or similar equipment, allowing the flow only in one direction and preventing flow reversal due to the back pressure.

The ball check valve can be used for a high viscosity fluid. The arrow stamped on the valves should match direction of the flow.

The sealing ability of check valves depends on the pressure of the back flow and the viscosity of the fluid.

FORGED STEEL, ALLOY AND STAINLESS STEEL

ENO offers this product line manufactured in accordance with API-602. and ANSI Classes 800, 1500 and 2500 for socket weld, threaded and combined ends. Also available are Integral Flanges in 150, 300, 600 and 1500 either Raised Face or ring type joint ends.
SINWA keeps a large quantity of these valves in stock in the most common trims used by the industry. For Certain Customer applications where forged material is not available (specifically for high nickel alloys), ENO has developed this product line using sand casting. In order to keep the same quality level as forged, these castings are produced with 10% of each lot to be subject to X-ray examination.
ENO offers the majority of materials known and used for this product line, including but not limited to:
  1. Carbon Steels A105.
  2. Low Carbon Steels LF2, LF3.
  3. Low Alloy Steels F1, F11, and F22.
  4. Medium Alloy Steels F5, F9, and F91.
  5. Stainless Steel Valves F304, F316.
  6. Low Carbon Stainless Steel F304L, F316L.
  7. Duplex Stainless Steel F51, F53.
  8. Nickel Alloys Inconel, and Monel. When cast steel valves are manufactured in accordance with API- 602. as an acceptable option, WALWORTH offers this product line in the following materials either socket weld, threaded or flanged ends:
  1. Stainless Steels CF8, CF8M, CF8C, CF10, CG8M.
  2. Low Carbon Stainless Steels CF3, CF3M, CG3M.
