OEM 5" WCB Two PCS Split Body Wafer Butterfly Valve Exporter, Exporters
Product Description
1. WCB Split Body
WCB is a durable material that is often used in general-purpose applications involving air, water, oil, and certain chemicals.
2. Split Design
Split construction is easier to maintain and repair. This design can improve the durability of the valve, extending its service life by better inspection and replacement of internal parts.
3. EPDM Seat
EPDM seat is a resilient rubber-like material that minimizes leakage and is suitable for drinking water, air, and weak acidic or alkaline media.
4. CF8M Disc
Performs well in corrosive environments and is ideal for use with corrosive fluids, including certain chemicals, seawater, and industries such as food processing, petrochemical, and pharmaceuticals.
