Butterfly Valve 500x500

Butterfly Valve has many advantages over gates, globes, plugs, and ball valves, especially for large valve applications. Savings in weight, space, and cost are the most obvious advantages. Maintenance costs are usually low because there is a minimal amount of moving parts and no pockets to capture fluid.

Horizontal Butterfly Valve has a short circular body, circular disc, metal or soft chair, top and bottom axle bearings, and stuffing box. The body construction of the butterfly valve varies. A commonly used design is a suitable type of wafer between two flanges. Another type, the design of a wafer lug, is held between two flanges with a bolt that joins the two flanges and passes through a hole beyond the valve casing. Butterfly valves are even available with flanged, threaded ends and butt tips, but they are not often applied
