Key Features
- Compact structure: wafer or flanged connection, small footprint for large-diameter pipes.
- Light operation: handle or gear drive for quick opening/closing.
- Flow adjustable: disc can stop at any angle for flow regulation.
- Industrial-grade corrosion resistance: body and disc are PVC-U/C; seat is EPDM or PTFE.
Manufacturing Process
Body and disc injection molded from PVC-U/C; seat lined with EPDM or PTFE. Reliable stem sealing; handle or gearbox operation.
Critical Process Parameters
- Disc-seat sealing fit accuracy.
- Stem sealing performance.
- Wafer dimensions conform to standards.
Raw Material Characteristics
- Body, disc: PVC-U or PVC-C
- Seat/Seal: EPDM or PTFE
- PVC-U suitable ≤60°C; PVC-C suitable ≤93°C
Typical Applications
- Shut-off and regulation in large-diameter chemical piping.
- Flow control in industrial water treatment systems.
- Corrosive fluid transport control in electroplating and semiconductor industries.
Application Scenarios
- Shut-off and flow regulation in large-diameter industrial piping.
