Trunnion ball valve with gearbox EN 558 carbon steel PN25

Trunnion ball valve

for high pressure oil and gas pipelines

VTC line trunnion ball valves

Trunnion mounted ball valves designed for oil and gas pipeline applications where high pressure, large diameters, and reliable isolation are required. These valves are commonly specified for transmission and gathering pipelines, providing stable operation, reduced torque, and long-term sealing performance under demanding service conditions.The trunnion-mounted design ensures controlled ball movement and minimizes seat wear, making this valve type suitable for critical pipeline isolation duties in EPC projects.
