Carbon Steel Trunnion Ball Valve 16 inch - 60 inch For Water Power Station

Carbon Steel Trunnion Ball Valve 16 inch - 60 inch For Water Power Station

Water Power Station Ball Valve (MIV ball valve  or Spherical valve)

MAIN FEATURES:

The Turbine Inlet valve has been designed three piece body type and with two floating seats, which are movable under the pressure of drive water or oil. When drive pressure increase under the bottom side of seats, the floating seat can attach the ball’s surface tightly, other more, When drive pressure decrease under the bottom side of seats, the floating seat can leave the ball’s surface.

The ball valve is equipped with the movable seat seal ring which can generate displacement under the pressure of drive medium. So that biggest size ball valve can be easy to drive by actuator and the sealing performance of the ball valve can to be control.

The ball valve is suitable for service of water power station main pipe-line system, or strictly at functional reliability system.
