1, the electric butterfly valve has the simple structure, the volume is small, light weight, material consumption province, small installation size, fast switch, 90° part of the rotation, small driving torque, etc., used to cut, connect, adjust the media in the pipeline, Valve electric butterfly valve manufacturers have manual, electric, with good fluid control characteristics and close sealing performance.
2, the electric butterfly valve may carry the mud, in the pipeline mouth accumulates the liquid to be few. Under low pressure, good sealing can be achieved. Good adjustment performance.
3, the electric butterfly valve stem is the pass pole structure, after the adjustment treatment, has the good comprehensive mechanical property and the corrosion resistance, the abrasion resistance. When the electric butterfly valve is open and close, the stem is only rotated without lifting and running, and the seal is reliable. Electric butterfly valve price and the butterfly plate cone pin fixed, pneumatic, hydraulic, electro-hydraulic linkage and other Executive Body electric butterfly extension end for the design, so as to avoid the valve stem and the butterfly plate connection accidentally break when the stem collapsed.
4, the electric butterfly valve connection Way has the flange connection, to the clamp connection, to the welding connection and the lug to clamp connection. The driving form has manual, electric, pneumatic, hydraulic, electro-hydraulic linkage and other executing agencies, can realize long-distance control and automation operation.
