]]> 1. Overview of Forged Steel Check Valve

VTON forged steel check valves are designed with three types of valve covers to suit various operational needs:

  1. Bolted Cover: The valve body and cover are connected with bolts and nuts, sealed with a spiral wound gasket (316 flexible graphite). Metal ring connections are available upon request.
  2. Welded Cover: The valve body and cover are threaded and fully welded for sealing. Penetration welding is optional.
  3. Pressure Self-Tightening Cover: The valve body and cover are threaded and sealed with internal pressure self-sealing rings.

Additionally, the valves are available in three structural types: lift check, ball check, and swing check valves, providing flexibility for different applications.

]]> 1. Overview of Wafer Check Valve

Wafer check valves are automatic valves that rely on medium pressure to open and close, ensuring smooth and secure flow in pipeline systems. Compared to traditional check valves, VTON’s wafer check valves are significantly smaller, lighter, and more efficient, addressing common issues such as high fluid resistance and water hammer pressure.

Applications:

  • Water systems
  • Petrochemical, chemical, and metallurgical industries
  • Oil, gas, and steam pipelines

2. Technical Parameters

  • Nominal Diameter (DN): 32 ~ 2000mm
  • Nominal Pressure (MPa): 0.6 ~ 32
  • Temperature Range (℃): -196 ~ 550
  • Material Options: WCB, SS304, SS316, WC6, WC9
  • Applicable Media: Water, oil, steam, natural gas, sulfuric acid, nitric acid, phosphoric acid, nitrogen, oxygen, hydrogen, and other gases
  • Connection Type: Wafer
  • Applicable Environments: Water systems, petrochemical, chemical, and metallurgical industries
  • Manufacturing Standard: VTON
