China Double Offset Butterfly Valve Manufacturers

What are Double Offset Butterfly Valve?

Double Offset Butterfly Valve are used in pipelines to automatically vent air or gas from water mains as the line is filled or drained. They allow air pockets to escape while preventing liquid loss, protecting systems from the damaging effects of entrapped gasses.

Benefits of Double Offset Butterfly Valve

• Prevent Backflow – The primary benefit is avoiding contamination of fluid source from back-siphoning or backpressure flows that could introduce unwanted materials.
• Flow Security – Non-return functionality gives confidence in downstream pressures without risk of reverse surge loads damaging pipes, tanks or equipment.
• Self-Acting Operation – No external power is required as valves from China Double Offset Butterfly Valve Manufacturers, automatically open and close based on differential pressures across the seat.
• Durability – Engineered valve designs withstand millions of pressure cycles without compromising barrier performance over decades of use.

Applications of Double Offset Butterfly Valve

• Municipal Water Systems: Often used to control flow and isolate sections for maintenance in drinking water distribution networks.
• Wastewater Collection: Open/close valves are critical for managing flow in sewers, pumping stations and treatment plants.
• Power Plants: Double Offset Butterfly Valve start/stop steam flow between boiler, turbine and flash tank vessels.
• Pulp & Paper Mills: Process fluid control for streams like brown stock, white water, bleaching chemicals etc.
• Mining Operations: Underground slurry and water pipelines rely on rugged gate valves to handle abrasive loads.
• Manufacturing Facilities: Ductile iron construction makes Double Offset Butterfly Valve perfect for flow regulation in industrial plants like chemical, food+beverage and refineries
