ZPL510WF Lined Bellows-Seal Control Valve. This valve features an enhanced stem sealing system that combines PTFE bellows sealing with V-shaped PTFE packing, creating a dual-seal structure that completely eliminates external media leakage through the valve stem.
The multi-barrier sealing design provides absolute containment, making it particularly effective for handling highly toxic media (such as chlorine gas and liquid chlorine) where zero-leakage performance is critical.

| Features | Description |
| Superior Corrosion Resistance | V-groove reinforced full lined flow path with compression-molded internals blocks corrosive media |
| Dual Sealing System | The integrated bellows-and-packing dual-seal system provides superior containment performance, eliminating hazardous media leakage risks |
| High-Strength Bellows | Imported "Daikin" TFM-1600 material provides the bellows with an exceptional elastic deformation range and superior corrosion resistance. |
| Adhesion Guarantee | The perforated reinforcement pattern on the disc/seat assembly enhances fluoropolymer-metal interfacial bonding, achieving tight sealing performance |
| Reliable Sealing Performance | The V-ring packing design delivers excellent sealing with low operating torque. Dual O-rings in the gland structure prevent media leakage along the valve stem. |
| Maintenance-Friendly | Removable bottom plate enables easy routine maintenance, allowing effective removal of accumulated crystals and impurities. |
