- Product Features & Options
- Split Body Design: The valve body consists of two halves bolted together, facilitating the molding process of the lining and allowing for easier liner replacement or maintenance.
- Fully Lined Construction: All wetted metal surfaces (including body passage, flange sealing faces, and disc) are encapsulated with fluoroplastic, providing excellent corrosion resistance.
- PTFE Seat: Provides low friction coefficient, excellent chemical resistance, and long service life. Suitable for most corrosive media.
- Lug Type Connection: The valve body has threaded lugs, allowing it to be bolted between flanges using studs. This permits dead-end service and allows removal of one side of the pipeline without affecting the other.
- Manual Operation:
- DN50-DN200: Standart Lever Handle, allowing variable opening positions with a locating pin to lock in fully open/closed positions.
- DN250-DN600: Standart Gearbox with self-locking function for easy operation, complete with a handwheel.
- Optional Configurations:
- Extended stem or extended lever handle (for insulated pipelines).
- Anti-static device (conforming to ISO 5211).
- Position indicator or limit switch.
- Installation & Maintenance Notes
- Ensure the disc is in the closed position during installation to avoid forcing alignment.
- Use corrosion-resistant gaskets (e.g., PTFE gaskets) for flange connections.
- Do not force the handle when the valve is fully closed to prevent damage to the PTFE seat.
- Regularly check the tightness of handle or gearbox mounting bolts and maintain lubrication.
Note: This data sheet provides general specifications. For specific projects, please refer to the manufacturer’s final drawings and parameters.
