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...
Stainless Steel API Wedge Gate Valve
Bolt Bonnet Gate Valve with flexible wedge disc are commonly used in all type of low pressure industrial pipelines in oil, gas and power station for the shut-off services and they have much advantages such as simple structure, short face to face dimension, lower flowing resistance as well as long time services with...
Manual Operated Wafer Knife Gate Valve
Knife gate valves are designed mainly for on-off and isolation services in systems with high content of suspended solids. The knife gate valves are especially beneficial for handling slurry, viscous, corrosive and abrasive media. The valves have a minimised pressure drop in fully open position, they are easy to...
