Product Feature

·Simple structure, small size, light weight, the number of spare parts is limited

·A mere 90 degrees rotation can realize fast-speed open-close, easy operation and good performance for controlling the fluid.

·When the butterfly valve is fully opened, the valve plate thickness is the only resistance as the mediums flow through the valve body, so the differential pressure is small.

·Better performance for controlling the flow
