OEM DN50 Dovetail Seat Double Shaft Wafer Butterfly Valve PN16 Factory, Exporters
Product Description
Ductile Iron Valve Body
Durable GGG50 ductile iron, offers higher tensile strength and impact resistance. It provides excellent pressure-bearing capability.
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.
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
EPDM Material Applications
EPDM material provides excellent performance for:
- Water systems
- Drinking water pipelines
- HVAC cooling systems
- Mild chemical media etc
Double Shaft
This design improves disc support and reduces shaft deformation during operation.
SS431 Stainless Steel Shaft
It combines good mechanical strength with corrosion resistance.
