Silicone Rubber Seat Butterfly Valve Applications
Water and Wastewater Management: Used to control the flow of raw and treated water.
Drinking Water Systems: EPDM valve seats ensure a sanitary, leak-proof seal and are suitable for drinking water pipes.
Irrigation Systems: Effectively control water flow in agricultural irrigation pipes.
HVAC Systems: Suitable for chilled water and hot water systems in pipes.
Fire Protection Systems: In sprinkler systems, it is often used as an isolation valve or flow control valve in fire water supply systems.
Food and Beverage Industry: EPDM valve seats are non-toxic and resistant to water-based liquids, making this valve suitable for food processing (excluding oil-based products).
Chemical Processing: Low-corrosive chemical systems, suitable for systems conveying weak acidic or alkaline solutions that are compatible with EPDM.
Power Plants: Cooling Water Systems, for cooling water flow management.
