The basic characteristics of electric butterfly valve

Electric butterfly valve has simple structure, small volume, light weight, material consumption province, small installation size, small quick, 90 ° reciprocating rotary switch, low driving torque, etc, used for truncation, connected, regulate medium in pipe has good flow control characteristics and close the sealing performance. Electric butterfly valve can transport the mud, and the apertures least accumulated liquid. Under low pressure, can achieve good sealing, good regulation performance. Electric butterfly valve disc streamline design, make the loss of the fluid resistance is small, is a kind of energy-saving products. Electric butterfly valve stem for stem structure, through conditioning processing, has the good comprehensive mechanical properties and corrosion resistance, abrasion resistance. Electric butterfly valve opening and closing valve stem rotation movement and not only for lifting operation, the valve stem packing is not easy to damage, reliable sealing. With the butterfly plate fixed cone pin, overhanging end to prevent rushed out of the design, in order to avoid in the stem and disc joint stem collapse accident broke out. Electric butterfly valve connection flange connection, connected to the clamp, the butt welding and lugs on the clip. Driving type is manual, worm gear drive, electric, pneumatic, hydraulic and electric hydraulic linkage actuator, which can realize remote control and automation.
