  • DESCRIPTION

     

    Advantages of electric flange ball valve:

    1. It can be applied to the situation of two-position shut-off control, and can also perform percentage adjustment on various parameters such as medium flow, pressure, temperature, etc.
    2. Select the explosion-proof type according to the working conditions, or install a manual handwheel device to realize the function of manually opening and closing the valve.

    3. The electric flange ball valve has ultra-low flow resistance, large flow capacity, convenient loading and unloading and maintenance, and excellent sealing performance. It is suitable for a variety of working conditions.

    4. The Q941H electric ball valve has small size, light weight, large thrust, built-in servo amplifier, easy operation and high reliability.

    5. The electric flange ball valve can have any flow direction and a wide adjustable range. It can be used in high-pressure and large-diameter situations to control high-viscosity media with fibers and fine particles.

    6. The electric actuator has a built-in servo system, no need for a separate servo amplifier, and the operation can be controlled by input and output signals of 4-20mA and AC380V power supply. It has the advantages of simple wiring, compact structure, and stable movement.
