产品描述

Electric operated trunnion ball valves are designed for upstream sealing. The load generated by the line fluid on ball is absorbed by the trunnion bearings and is directly transmitted to the valve body, and the upstream seat driven by medium pressure drifts towards the ball to creater reliable sealing. The seat design has a built-in automatic cavity relief mechanism. Comparison with floating ball valve, trunnion ball valves have emergency seat injection fitting for size bigger than 4″ and the sealing of trunnion ball valve is much more reliable than floating type, the seat was inserted into a steel retainer, and the retainer surported by the spring, so to keep the seat with enough  pretightening force. Even the sealing face wearing out, it still seal good.
