Features:
Lug type butterfly valve can be manual, worm gear, pneumatic, or electric. The connection method can be flange or clamp, and the structural form can be single eccentric, central eccentric, double eccentric, or triple eccentric. The sealing structure can be soft or hard sealed, with a pressure range of 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 type of valve has different combinations in different occasions and working conditions. The butterfly plate of the stainless steel wafer type lug butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc shaped butterfly plate rotates around the axis, with a rotation angle between 0 ° and 90 °. When rotated to 90 °, the valve is in a fully open state.
