Trunnion Ball Valve Top Entry – Rising Stem
Trunnion Ball Valve Top Entry – Rising Stem
Operating Description: The movement of the ball tilted from the seat before starting the rotation eliminates the wear of the seat seal and allows for smooth movement and low torque. The same tilting movement when starting the opening allows for a cleaning flow all around ball surface; this flow automatically flushes the ball surface removing eventual dirt particles from the sealing areas.
MATERIALS OF CONSTRUCTION: Low Temperature and Low Alloy Carbon Steel, Stainless steel, Duplex and Super Duplex, Nickel alloys
