Forged Steel Ball Valve made by Centro Flow is a very common type one among ball valves, the structure of trunnion ball valve is opposit to a floating one with ball fix installed to the stem on one end, and the other end ball connected to trunnion. This Centro Flow Trunnion ball valve made strictly comform to the Global standard and customized specifications. And products fully controlled under management ISO 9001 and standard API. For more information please don’t hesitate to contact us imm.
Construction of Centro Flow Forged Steel Ball Valve is of a heavy duty 3-piece bolted body structure, designed to meet or exceed the requirements of most demanding applications. Its a floating seat ring, self-relieving seat design. The seat are contained in metal carries with spring loaded against ball, while the two independent floating seat rings assures bi-directional tightness of the valve from zero differential pressure to the maximum rated pressure. When valve be in a closed position, media will be trapped in the body cavity, unless this media is drained, it will be subject to thermal expansion and contraction. During the temperature rises, the trapped media desires to expand and the pressure increases in the body cavity. In order to avoid excessive pressure built-up, the Centro Flow valve seats are designed to self-relieve, allowing the media in the body to escape into the pipeline.
