EPDM Coated Wafer Butterfly Valve
Advantages of EPDM Coated butterfly valve
- Advanced sealing: EPDM Coated butterfly valve can effectively prevent leakage. it can ensure that fluid will not leak or penetrate into the valve structure, improving the safety and efficiency of the system.
- Compact and lightweight, wafer butterfly valves are easy and cost-effective to install, making them ideal for use in systems with limited space.
- Wafer connections fit between standard flanges (e.g. ANSI, DIN, JIS) without the need for additional brackets or supports.
- Wafer centerline butterfly valves are suitable for bidirectional flow control.
- Hard back seat: Provides a durable sealing surface to ensure tight closure, prevent leakage, and will not misalign.
- Worm gear operators: Provide precise manual operation and flow control.
- Corrosion resistance: The outer layer of the valve disc is coated with EPDM material, which can withstand the erosion of various chemicals and corrosive media.
- Wide application: EPDM coated wafer butterfly valve is suitable for fluid control and treatment in various fields, such as water treatment, the chemical industry, petroleum, pharmaceutical, food, etc.
