Trunnion Side Entry Ball Valves
Optimal Performance for Critical Applications
Trunnion Side Entry Ball Valves are designed for critical applications across the upstream, midstream, and downstream Oil & Gas sectors. These valves feature a 2- or 3-piece bolted body and are available in metal-seated or soft-seated designs. The trunnion-mounted configuration ensures high-pressure reliability, enhanced sealing, and reduced risk of seat deformation. Optional Double Block and Bleed (DBB) or Double Isolation and Bleed (DIB) functions provide additional operational safety.
Engineered for durability and reliability, these valves deliver long service life under both high and low pressure conditions.
