GFI Butterfly Valves
GFI Butterfly Valves are compact quarter-turn valves designed for reliable isolation and flow control across a wide range of industrial piping systems. A centrally mounted disc rotates through 90 degrees to open, close, or regulate the flow of the process medium.
Their lightweight construction, compact installation footprint and low operating torque make Butterfly Valves an efficient solution for large-diameter pipelines. GFI offers wafer, lug and flanged configurations along with resilient-seated and high-performance designs for different pressure, temperature and service conditions.
Key Features
Quarter-Turn Operation
The disc rotates through 90 degrees for quick opening and closing, making the valve suitable for efficient isolation and automated operation.
Compact & Lightweight Construction
The compact body requires less installation space and reduces overall valve weight compared with many conventional full-size isolation valves.
Low Operating Torque
Optimised disc and seat designs help minimise operating torque and support efficient manual or actuator-driven operation.
Reliable Shut-Off
Resilient and metal-seated configurations provide dependable sealing for different industrial isolation requirements.
Wide Size Availability
Butterfly Valves are particularly suitable for large-diameter pipelines where compact design and economical operation are important.
Actuation Ready
Available with manual, pneumatic, electric or other suitable actuation arrangements for automated process control.
Available Types
Wafer Type Butterfly Valve
Compact and economical design installed between pipe flanges. Ideal for general isolation and flow-control applications where space and weight are important considerations.
Lug Type Butterfly Valve
Features threaded mounting lugs that allow the valve to be installed and removed independently from either side of the piping system.
Double Flanged Butterfly Valve
Robust flanged construction designed for larger pipelines and applications requiring secure connection and structural support.
High Performance Butterfly Valve
Offset disc and shaft arrangement reduces seat wear and operating torque while providing dependable shut-off for demanding services.
Triple Offset Butterfly Valve
Cam-action disc movement minimises seat contact during operation and provides a suitable solution for high-temperature and demanding process services.
Resilient Seated Butterfly Valve
Elastomer-lined or resilient-seat construction provides effective sealing for water, HVAC, utility and general industrial applications.

Butterfly Valve Applications
GFI Butterfly Valves are widely used for isolation and flow-control applications in water treatment, wastewater systems, industrial utilities, HVAC, oil and gas, petrochemical, power generation and general process industries.
Their compact construction and quarter-turn operation make them especially suitable for large-diameter pipelines where reduced installation space, lower weight and efficient operation are important.
Resilient-seated Butterfly Valves are well suited to water and utility services, while high-performance and triple-offset configurations can be selected for more demanding pressure and temperature conditions.
