Butterfly Valve

Butterfly valves for fire protection start, stop or throttle the flow of water through the rotation of an internal disc. The disc’s rotation is typically controlled by a handwheel. Valves equipped with the Handwheel Gear Operator are closed by turning the handwheel clockwise and opened by turning the handwheel counter-clockwise.

Compared to other types of control valves, butterfly valves are relatively lightweight. Their simple, straightforward design also makes them easier to install, maintain and repair.

Butterfly valves are a good alternative to Ball Valves since they use less space resulting in less material and a much lower cost.

This valve painted in red, are fitted with a specially designed gearbox. A yellow flag of 100 x 100 mm, which is also visible from a distance, indicates if the butterfly valve is open or closed. As an option, the gearbox can be fitted with two internal limit switches.
