Forged Steel Pressure Seal Check Valve

The most recent software-based analytical techniques were used throughout the design process of GMK’s forged pressure seal check valves. All of the projects are assessed utilizing techniques for three-dimensional solid modeling throughout the design phase. The benefits include a decrease in the amount of time and expense spent developing the product, as well as an improvement in product quality. In the development stage, we utilize something called finite element analysis, or FEA, to make sure the valve will fulfill all of the design performance criteria. The valves are inspected for any difficulties with their functionality, as well as any material deformation or flow-related stresses.

The use of finite element analysis (FEA) to forecast failure owing to unknown stresses inside the GMK Forged Steel Pressure check valve body is a preferable approach to evaluating the product since it saves money on manufacturing expenses and on testing in the real world. Weld quality is checked using ultrasonic or radiographic analysis. In terms of strength and consistency, forgings are widely acknowledged to be superior than castings. This occurs because the forging process induces continuous flow lines, which are especially important in the very crucial regions at the interface between two distinctly different volumes.


  •  Non-return valve seals well.
  •  Medium-specific sealing materials may improve valve sealing and wear resistance.
  • The flanged forged steel pressure seal check valve closes with little twisting.
  •  Surface friction is low.
  •  Valve body precision casting and CNC machining.
  •  Disc restrainer prevents discs from opening too high to close.
  • A high-strength solid pin is properly inserted, ensuring valve performance and longevity.
  • The disc-closing rocker is strong and flexible.
