BUTTERFLY VALVE GEAR TYPE

Valves

Coating: RAW / BLACK PAINT

Available Size: 1/2" - 12"

🔎 What It Is:

A Gear-Type Butterfly Valve is a quarter-turn valve that uses a circular disc (the “butterfly”) to regulate or isolate flow. In gear-operated models, the valve is manually controlled using a gearbox and handwheel, which allows for easier operation in larger sizes or high-pressure applications by reducing the torque required to turn the disc.
