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.
