Butterfly Valve – Key Features & Advantages
Compact & Lightweight
Ideal for large-diameter pipelines where weight reduction lowers installation costs.
Low Torque Operation
The disc rotates parallel or perpendicular to flow with minimal actuator effort, suitable for manual or automated systems.
Economical Choice
Lower material and maintenance costs compared to gate or globe valves of equivalent size.
Versatile Performance
Compatible with water, gases, and moderate-viscosity fluids across HVAC, wastewater, and chemical industries.
Central Disc & Shaft
The disc is fixed on a shaft spanning the pipe diameter, connected to an external actuator (lever, gear, or pneumatic/electric drive).
Bidirectional Sealing
Resilient seat materials (EPDM, Nitrile, PTFE) ensure leak-tight closure in both flow directions.
Space-Saving
Slim profile fits tight spaces without compromising flow capacity.
Butterfly Valve – Efficient Flow Control for Cost-Sensitive Applications
A butterfly valve is a quarter-turn valve that regulates flow using a rotating disc mounted on a central shaft. Similar to ball valves, they enable rapid shut-off with a 90° actuator rotation, but excel in cost-effectiveness and lightweight design, requiring minimal structural support.
