GWC Trunnion Mounted Ball Valves

GWC ball valves have been developed for oil and gas pipelines, and process industry use according to API-6D standards. GWC Trunnion Ball valves are designed with a secondary metal-to-metal seal after a fire. When the primary soft seals are destroyed by fire, the fire-safe seals energise the seat assembly to seal. The differential seat area energized by line pressure with the spring force loads the seat into the ball. All GWC Model FF and GG Trunnion Mounted ball valves have been tested to API-607/API-6FA.

GWC forged body trunnion mounted ball valves are designed, constructed and tested according to API-6D. The full range of GWC Trunnion Ball Valves are supplied standard in full compliance with NACE MR-01-75.
