Description

Trunnion ball valves feature a robust design where the ball is anchored by trunnions to prevent axial displacement in the flow direction. As line pressure increases, the seat compresses against the ball, ensuring reliable sealing at the contact surfaces. Standard trunnion construction includes automatic cavity relief to handle overpressure within the valve body, making them suitable for a wide range of applications across all sizes and pressures.
