2-36 Inch Trunnion Mounted Ball Valve Class 150-2500 PN 16-420

2 - 48 inch High Pressure Ball Valve Forged Steel PEEK Seat Class 2500 PN420

High-Pressure Ball Valves

The high pressure ball valve is specially built for endurance and reliability with a design pressure of up to ANSI Class 2500 (420 bar / 6000 psi). As standard, the high pressure series is made from forged or rolled bar material, which could make sure sufficient rigidity and strength under maximum rated operation pressure, without the inherent flaw of cast. Standard wall thickness of separate body and adaptation of high strength tie bolts are convenient for valve maintenance and sufficient to bear the stress of pipe.

The high pressure ball valve delivers reliable performance in the most demanding applications in the oil & gas, offshore drilling platform, petrochemical and the power industries.

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.
