✨ Key Product Advantages
- Material Integrity: All Stainless Steel components (304/316, etc.) are guaranteed to meet material specifications (chemical analysis assurance) and material certificates are available upon request.
- Precision Manufacturing: Both the valve body and internal parts are processed using CNC precision machinery, ensuring high accuracy and smooth operation.
- Reliable Sealing: The rubber valve seat is made of compliant EPDM (Ethylene Propylene Diene Monomer) rubber, providing stable and reliable elasticity and tensile strength. Guaranteed to achieve zero leakage after ≥ 10,000 open/close cycles.
- Corrosion Resistant Fasteners: All standard fasteners (bolts, nuts) are made of Stainless Steel for enhanced corrosion resistance.
- Dual Pressure Testing: Every valve undergoes strict national standard dual pressure testing (shell and seal tests) before leaving the factory to guarantee performance and safety.
