Butterfly valves belong to the category of quarter-turn valves and work fundamentally the same as ball valves. The butterfly is a disk connected to a rod; it closes when the bar pivots the disk a quarter turn opposite to the flow direction and opens to permit flow.
Motorized butterfly valves offer good control over processed media moving through pipelines. They can rapidly respond to demands to start, stop or modulate flow, and the resulting flow lines up with the best outcomes.
Motorized butterfly valves are manufactured in a wide range of sizes — from a few inches to several feet — so manufacturing plants can fit them inside specific pipelines. Entellus is a stockist and distributor of Valvulas Zubi and L&T valves.
Types: Lug-Style, Wafer-Style, Double-Flanged and Butt-welded butterfly valves — each suited to specific service conditions including dead-end isolation, bi-directional pressure, throttling and high-pressure welded installations.
