Fifth, good sealing. The sealing performance is mainly reflected in the advantage of two-way sealing. Even in the installation process, it is not affected by the flow direction of the fluid at all, let alone the spatial position. The overall baking paint can be installed in any direction to effectively avoid corrosion. 　　

The so-called electric on-off butterfly valve actually refers to the mutual combination of the electric actuator and the butterfly valve. Through ± 5 ° fine-tuning and the use of the internationally common SIO05211 connection standard platform, it can achieve the valve of precise matching. The electric on-off butterfly valve has been widely used in this era. The electric actuators mentioned here are classified into intelligent adjustment type, explosion-proof type and flameproof type in special environment according to the stroke torque control with rotation angles of 90 °, 120 °, 180 ° and 270 °. The power supply of the actuator is
