Trunnion style ball valves available in 1, 2 and 3 piece designs for very demanding applications
Highly engineered trunnion style ball valves available in 1 piece, 2 piece and 3 piece designs for very demanding applications typical of oil and gas pipelines, including piggable service. The TM style valves are used for natural gas storage systems, gas transmission, LNG, HRSG, subsea oil refining, desalination CO2 service and power generation applications.
Available with metal or polymeric seated balls and bodies made of Carbon steel, Low Temperature Carbon Steel and 316SS, our trunnion valves provide reliable sealing across a range of temperatures and pressures. The applicable design specifications include API 6D, ASME B16.5/B16.10/B31.1/B31.3, FCI 70-2-1976, PED 97/23/EC, BS 2080, ISO 5752, MSS-SP-6/25/44, ASME B16.34 and NACE MR-0175. Testing standards include API 598, API 607, BS 6755 PART 2, Fire Safe and MSS-SP-55. The facility manufacturing the trunnion valves is registered with ISO 9001, CE Certified and API Q1.
Seats are spring loaded and seal individually on both upstream and downstream sides of the ball
The valve seat springs are encased in a protective structure to prevent impurities from interfering with spring operation.
If the seat and stem seals become damaged, emergency injection fittings can be used to create a temporary back-up seal.
