600LB Cast steel trunnion ball valve

600LB Cast steel trunnion ball valve Product introduction

　600LB Cast steel trunnion ball valve is equipped with trunnion seat, after being subjected to medium pressure, the seat of 600LB Cast steel trunnion ball valve produces movement, so that the sealing ring is pressed tightly on the ball to ensure the seal. Usually on top of the ball, the lower shaft is equipped with bearings, the operating torsion distance is small, suitable for high pressure and large caliber valves. In order to reduce the operating torque of the ball valve and increase the reliability of the seal, oil seal ball valve has appeared again in recent years, not only in the sealing surface pressure injection special lubricating oil, to form a layer of oil film, that is, enhance the sealing, but also reduce the operating torque, more suitable for high pressure large caliber ball valve.
