Product Advantage
1. Ductile iron valve body: durable GGG50 ductile iron, offers higher tensile strength and impact resistance. It provides excellent pressure-bearing capability.
2. CF8 stainless steel disc: delivers strong corrosion resistance and reliable mechanical performance . The Milwaukee-type disc design helps reduce flow resistance and improves sealing efficiency during operation.
3. Dovetail Seat: The soft EPDM dovetail seat is one of the key advantages of this valve:
Easy replacement without replacing the whole valve
Lower maintenance cost
Strong sealing performance
Anti-blowout seat structure
Better resistance to seat movement under pressure
4. EPDM material provides excellent performance for Water systems, Drinking water pipelines, HVAC cooling systems , Mild chemical media etc
5. Double Shaft: this design improves disc support and reduces shaft deformation during operation.
6. SS431 Stainless Steel Shaft: it combines good mechanical strength with corrosion resistance.
