6. 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: Standar Lever Handle, allowing variable opening positions with a locating pin to lock in fully open/closed positions.
• DN250-DN600: Standar 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.

7. 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.
