As a Wafer Butterfly Valve Manufacturer, share with you.

The driving mode of the lug type butterfly valve can be manual, worm gear, pneumatic, electric, the connection mode can be flange, butt clamp, the structure can be single eccentric, center line, double eccentric, triple eccentric, and the sealing structure can be soft seal or hard. Sealed, the pressure range is PN0.1-10Mpa, the nominal diameter is DN40~2000mm, and the material can be cast steel or stainless steel.

Due to the wide range of use of valves, the same valve has different collocations on different occasions and working conditions.

Wafer Lug Type Butterfly Valve

Wafer Lug Type Butterfly Valve

The butterfly plate of the wafer-type lug butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0°-90°. When the rotation reaches 90°, the valve is in a fully open state.

structure

The wafer butterfly valve is connected between two pipe flanges with stud bolts. Its structure is simple, small in size and light in weight, and it consists of only a few parts. Moreover, it can be opened and closed quickly by rotating 90°, and the operation is simple. At the same time, the valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is small, so it has better flow control characteristics. The butterfly valve has two sealing types: elastic seal and metal seal. Elastic sealing valve, the sealing ring can be inlaid on the valve body or attached to the periphery of the butterfly plate.
