Product Description
FREE-VALVE Manual Hand Lever Plastic CPVC PVC UPVC 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.
- Main components made from corrosion-resistant polymeric materials,lightweight.
- Compact in design,making it ideal for tight spaces.
- Easily assembled with perfect sealing.
- The wafer body is placed between pipe flanges, and the flange bolts surround the valve body.
- Blow-out proof one-piece stem assembly.
- Equal percentage type throttling characteristic.
- Mechanically locked in handlever.
