Forbes Marshall Piston Valves are the best technical fit to cater to a variety of fluid isolation applications in the industrial sector. They find application in a variety of media in processes and utilities like saturated steam, superheated steam, heat transfer fluids, nitrogen, and more.
Our piston valves are unique in their ability to provide a perfect inline shut-off and no gland leakage. This ensures zero inline/external leakage.

  • 480 to 600 % higher sealing area.
  • Class VI bubble tight shut off: burnished piston sealing.
  • Zero gland leakage, Soft seated Sealing
  • Perfect interface fit, Interchangeable parts
  • Protection of wetted parts: In the open and closed conditions, the piston remains enclosed in sealing rings and is hence protected from erosive or corrosive material.
  • Zero inline leakage
  • Class VI bubble tight shut off
  • Zero gland leakage
  • Perfect interface fit
