Product DescriptionProduct Description
Forged Steel Trunnion-mounted Ball Valve Nps8 Class1500 Double Block & Bleed (DBB)
The trunnion mounted ball valve has been designed with two floating seats, which are movable under the pressure of medium. Under the bottom of seats, seat pre-loading springs are positioned to ensure two floating seats attach the ball surface tightly. The ball is fixed by upper and lower trunnions, so the seat rings don't afford too much flow pressure force when valve is in closed position. During service, pressure of medium pushes the front seat against the ball, forming a bubble tight seal.

5. Structure & Advantages
KATA ball valves are all designed with reasonable dimensions and outlook. It's size ranges from 2" to 56", with pressure rating from class 150 to class 2500. From 6'' and above, it's all designed with support plate structure instead of trunnion mounted. This design can greatly reduce the torque and external leakage point of the valve, ensuring that the drain valve at valve bottom is installed directly below the valve, so that residue can be completely drained when the valve works to clear the pipe.6.
