BUTTERFLY VALVE

High performance butterfly valves  can be used widely for automatic proportion control, simple and clear valve structure enables user to assemble and disassemble easily.

 valves are classified as Wafer Type, Lugged Type and Flanged end type. Their principal parts are consisting of body, disc, seat and materials of each part are different according to the working condition.

Butterfly valve is much smaller than other valve designs. The results are saving in materials, less weight, small space requirement, and easy installation and operation.
