FORGED STEEL TRUNNION BALL VALVE

Trunnion Mounted Ball Valves is forged Steel Line are available in types of Two Piece Split Body & Three Piece Bolted Body. The forging material can ensure sufficient rigidity and strength under maximum rated operation pressure. Without inherent flaw of cast. Enough 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 internal parts of valve are carefully designed and selected to ensure reliability under all kinds of work conditions.

This type of valve is designed to prevent backflow by allowing the flow of fluids through it. Its stem is connected to a slot on the ball’s top. The ball rotates laterally in response to upstream pressure, and the stem connects it to the ball. The ball’s lateral movement is regulated by seals on the stem and seats to prevent leakage. Floating ball valves are capable of bi-directional shut-off, but they’re difficult to operate when pressure is high upstream.
