Product Description

FREE-VALVE PVC/UPVC Plastic EPDM Seat Wafer Type Pneumatic/Manual 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. 
Features

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:
