What Are Double Flanged Butterfly Valves?

Double flanged butterfly valves are robust quarter-turn flow control devices featuring dual integral flanges on each side of the valve body. These flanges provide exceptional mechanical stability, flanged-to-flanged sealing, and straightforward alignment in high-pressure piping systems. The disc—mounted using resilient or eccentric design principles (e.g., double eccentric)—rotates to modulate or block fluid flow with precision and reliability.

Advantages of Double Flanged Butterfly Valves

Superior Structural Integrity & Alignment
Unlike wafer-style valves, double flanged valves are bolted directly to pipe flanges, ensuring stronger mechanical anchorage and optimal centering under varied loading conditions.

Double-Eccentric Design Enhances Longevity
The double-offset disc geometry decouples the seal during opening—minimizing frictional wear and ensuring longer service life with reduced operating torque.

Low Friction & Extended Seal Life
Seals are engineered (e.g., optimized EPDM or replaceable stainless steel seats) to maintain tightness while lowering torque. Double eccentric designs help preserve seal integrity over repeated cycles.

Reliable Maintenance Access
Flanged ends allow easy disassembly and seat replacement—ideal for frequent maintenance without disturbing adjacent pipework.

Wide Material and Pressure Compatibilities
Available body materials include cast iron, ductile iron, alloy steels, and stainless variants. Offered in ratings from PN10 up to PN40 and AWWA/ANSI Class designations. Options for soft seal (e.g., EPDM, NBR) or metal seat ensure wide compatibility .

Uses of Double Flanged Butterfly Valves

Primary Isolation in Industrial Pipelines
Used for quick shut-off in HVAC systems, water treatment, chemical dosing, and fluid processing—especially where structural rigidity is paramount.

High-Impulse and Regulated Flow Control
Effective where rapid actuation, low friction, and precise throttling are required, such as in pump lines and control manifolds.

OEM and Retrofit Valve Installations
Convenient for pipeline assemblies requiring modular installation and efficient serviceability.

Heavy-Duty and Corrosive Conditions
Suits applications across municipal water distribution, seawater, process industries, and demanding infrastructure including desalination or utility pumping stations.

Industries That Use Double Flanged Butterfly Valves

Water & Wastewater Treatment & Distribution
Oil & Gas Process and Transport Systems
Chemical and Petrochemical Plants
Power Generation and Utility Plants
Marine, Offshore, and Desalination Facilities
