U Type Flange Butterfly Valve
The U-Type Flange Butterfly Valve is a compact, reliable valve for flow isolation and control in industrial and water pipelines. Its U-type flange body is lightweight and space-saving, with dependable sealing. A concentric disc-and-shaft design and elastomeric seat ensure reliable shutoff for common liquids and gases. Simple construction allows easy operation, maintenance, and actuator installation
It supports manual lever, worm gearbox, pneumatic, or electric actuation for manual or automated systems. Applications include water supply/distribution, wastewater, HVAC/chilled water, cooling water, industrial water/piping, fire protection, marine, air/low-pressure gas, and utility pipelines.
Body, disc, shaft, and seat materials can be customized for the medium, temperature, pressure, and corrosion conditions.

Frequently Asked Questions
Everything you need to know about double eccentric butterfly valves, including design features, materials, applications and performance.
What is a U Section Flanged Butterfly Valve?
A U Section Flanged Butterfly Valve is a flanged butterfly valve featuring a U-section body design. It provides a compact structure, reliable sealing, and efficient flow control for industrial and water pipeline systems.
Is this butterfly valve designed according to EN 593?
Yes. The valve is designed in accordance with EN 593, which specifies requirements for industrial metallic butterfly valves, including design, construction, and functional characteristics.
What is the advantage of the U Section valve body design?
The U-section body provides a robust and compact construction while maintaining a relatively low flow resistance. It is suitable for applications requiring reliable shut-off and frequent pipeline operation.
What pipeline connection does the valve use?
The valve uses a flanged connection, making it suitable for installation between matching pipeline flanges. Flange dimensions and drilling can be customized according to the required standard and pressure class.
What media can this butterfly valve handle?
The valve can be configured for water, air, wastewater, and other compatible industrial fluids. The appropriate disc and seat materials should be selected according to the medium, temperature, pressure, and corrosion conditions.
