ZPR710F Lined 0-Port Shut-off Ball Valve is a 90° rotary quarter-turn shut-off valve. All wetted components (valve interior and internals) are lined with fluoropolymer via high-temperature molding, completely isolating the metallic valve body from corrosive media.
This design effectively prevents corrosion on all metal flow path components while delivering: Excellent sealing, Rapid actuation, Precise flow control. When paired with pneumatic actuators, solenoid valves, and limit switches, it achieves reliable on/off control. The valve is optimized for aggressive media: Acids, Alkalis, Salts, and so on.

| Features | Description |
| Superior Corrosion Resistance | V-groove reinforced full lined flow path with compression-molded internals blocks corrosive media |
| High-Rigidity Plug & Stem | Forged-welded ball & stem assembly ensures structural rigidity while eliminating casting imperfections |
| Micro-Clearance Fit Structure | Micro-clearance insert design for body/bonnet/packing box prevents fluoropolymer deformation, eliminating external leakage |
| Adhesion Guarantee | The perforated reinforcement pattern on the ball enhances fluoropolymer-metal interfacial bonding, achieving tight sealing performance |
| Reliable Sealing Performance | The "Daikin" TFM-1600 seat and V-ring packing provide excellent sealing with low operating torque, while the dual O-rings in the gland structure ensure zero external leakage along the valve stem. |
| Standard Mounting Platform | One-piece body/bracket ensures stable operation with IS0 5211-compliant actuator mounting. |
| High-Strength Stem Connection | The connection shaft is manufactured from Grade 45 steel or 2Cr13 alloy through hot-forging and CNC center machining, ensuring precise fit and enhanced rigidity. |
