Cycle Water Soft Seal Butterfly Valve
Butterfly valve is from a family of valves called quarter-turn valves. In operation, the valve is fully open or closed when the disc is rotated a quarter turn. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve...
Trunnion Mounted 3 pieces Ball Valve
The ball of Trunnion Ball Valve is fixed, it does not move with medium pressure and trunnion ball vale has floating seats. The seats move with the medium pressure to tight the ball and seal ring to ensure sealing reliability. Bearings could be mounted in top shaft and bottom shaft, which reduces operation torque. A...
The high-performance Double Offset Butterfly Valve, used in slightly higher-pressure systems, is offset from the centre line of the disc seat and body seal (offset one), and the centre line of the bore (offset two). This creates a cam action during operation to lift the seat out of the seal resulting in less friction...
