Ball Valve manufacturers Introduction锛?/strong> The Hiton HQ-series Pneumatic Trunnion Ball Valve is an economical and high-performance quarter-turn valve. The quarter-turn operation is fast and reliable which makes this valve applicable to quick on-off operation and tight seal. This ball valve is widely used in pulp paper refinery, mining, chemical fiber, sewage and water treatment, sugar refining industry. Size Range:DN 25~500mm NPS 1鈥?20鈥?/p> Press.

Body锛?/p> a) Full-bore design of valve body ensure biggest flow capacity and low flow resistance against media. 2. Core锛?/p> a) The trunnion mounting ball design prevents seat damage and reduces seat ware dramatically comparing with floating ball valve. b) The ball is precisely machined to mirror finish. And this contributes to bubble-tight shutoff and less operating torque. 3. Seat锛?/p> a) With seats on both sides锛宼he trunnion ball valve can handle flow in both directions with 0 leakage. Seat is spring preloaded, which ensures self sealing adjustment when flow pressure changes to achieve 0 leakage. 4. Stem锛?/p> a) With upper and bottom bearings for positioning, contributes to high mechanical stability, small required initiation torque. The self-lubricate bearing prevent valve from stuck. b) One, the trunnion ball design, with upper and bottom bearings for positioning, contributes to high mechanical stability, small required initiation torque. The self-lubricate bearing prevent valve from stuck. Product videoBall Valve manufacturers website:http://www.hsv-valve.com/ball-valve/
