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 process 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.

Features

 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 open and closed condition, piston remains enclosed in sealing rings and is hence protected from erosive or corrosive material.
