FREE-VALVE centric plastic butterfly valves consist of a disc-shaped butterfly plate mounted at the center axis of the pipeline, which is rotated to open, close, or throttle the flow,the valves are quarter-turn valves with equal percentage type flow characteristics ,its provide moderate flow control and therefore can be used in both on-off and regulating services in a system.
1.Main components made from corrosion-resistant polymeric materials,lightweight.
2.Compact in design,making it ideal for tight spaces.
3.Easily assembled with perfect sealing.
4.The wafer body is placed between pipe flanges, and the flange bolts surround the valve body.
5.Blow-out proof one-piece stem assembly.
6.Equal percentage type throttling characteristic.
7.Mechanically locked in handlever.
8.Working temperature: FRPP -14ºC~ +90ºC,UPVC -10ºC~ +60ºC,PVDF -40ºC~ +150ºC,CPVC -20ºC~ +95ºC
FREE-VALVE Centric Plastic Butterfly Valves are ideal for a variety of service conditions where both on-off and throttling are desired. They are used widely in Water treatment, Power plants, Marine, Electroplating, Chemical process industry, Automotive industry, Cooling equipment, Aquariums, Swimming pool construction etc.
