New Generation Trunnion Soft-Seated Ball Valves

Trunnion Ball Valve
Key Features and Benefits
(4" through 12") (ASME 1500, ASME 2500, API 10k)
  • Spring loaded seats for superb low pressure sealing
  • Stem seal seals to body and stem to reduce external seals
  • Stem retained by body not a bolted bonnet
  • Retainers threaded to body using stub Acme thread- makes valve pressure containing without flange installed
  • Large flange gap allows for three-part paint system installation to prevent corrosion
  • Trunnion mounted ball for low torque operation
  • Retainer threaded to the body using a Stub Acme thread for durability and strength. This makes the valve fully pressure containing with either end connection removed. Retainers are Xylan coated for corrosion protection and ease of maintenance.
  • Stem is retained by a shoulder in the body, not the bonnet, making the stem fully blow-out proof.
  • New Generation Trunnion Mounted Compact Ball Valves have dedicated, built-in automation mounting locations in the valve bonnet to allow field installation of automation without loosening any pressure containing fasteners. Many conventional compact valves require removal and reinstallation of bonnet fasteners in order to install actuator mounting hardware.
  • New Generation Trunnion Mounted Compact Ball Valves have double block and bleed capability as standard. Each valve body is fitted with a stainless body bleed fitting allowing easy bleeding of the body cavity when desired.
