Product Description

Construction of Centro Flow Trunnion Ball Valve is of a heavy duty 2-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.
