Backrest-Seated wafer Butterfly Valve

The butterfly plate of a wafer-type butterfly valve is installed in the diameter direction of the pipe. Within the cylindrical passage of the valve body, the disc-shaped butterfly plate rotates around its axis, with a rotation angle between 0° and 90°, achieving flow regulation. When the plate rotates to 90°, the valve reaches its maximum opening. <br/> Wafer-type butterfly valves have a simple structure, small size, and light weight, consisting of only a few parts. They can be quickly opened and closed with a 90° rotation, making operation simple. The valve also has good fluid control characteristics; its structural principle is particularly suitable for manufacturing large-diameter valves. <br/> Wafer-type butterfly valves are widely used in coal chemical, petrochemical, rubber, papermaking, and pharmaceutical pipelines as flow splitting, merging, or flow direction switching devices; the valve body is made using precision casting for a smooth surface without burrs or pinholes.

Electric Flanged Butterfly Valve

The butterfly valve is compact, lightweight, easy to disassemble, maintain, and can be installed in any position. <br/> It features a simple and compact structure, low operating torque, and quick 90° rotary opening; the sealing structure uses a composite seat made of polytetrafluoroethylene, synthetic rubber, and phenolic resin, giving the seat both elasticity and strength. The butterfly plate is fully wrapped in polytetrafluoroethylene, providing strong corrosion resistance. <br/> It has a linear flow characteristic and good regulation performance. The connection between the butterfly plate and the stem uses a pinless structure, eliminating potential internal leakage points. <br/> The outer circle of the butterfly plate uses a spherical design, improving sealing performance and extending the service life of the valve; it maintains zero leakage after more than 50,000 pressurized openings and closings. <br/> The sealing element is replaceable and provides reliable, bidirectional sealing. <br/> The butterfly plate can be coated with various materials such as nylon or polytetrafluoroethylene according to customer requirements.
