Trunnion Mounted Ball Valves

 

Forged trunnion ball valves are an excellent choice for on/off service in large and high pressure applications because the ball is anchored at the top and bottom of the design. Bonney Forge is a trunnion mounted ball valves manufacturer in an extensive range of designs, materials, sizes, pressure classes and end connections that are designed in accordance to ASME B16.34 and where applicable API 608, API 6D or BS EN ISO 17292. The valves are fire-safe test approved and include design features to ensure electrical continuity between ball, stem and body. Cryogenic and high temperature metal seated configurations are also available. All designs are forged for improved mechanical properties, pressure retention, and quality.
