Electric sleeve control valve takes single-phase AC 220V power as action force, receives 0~10mA DC signal, automatically control the opening of valve, thus realize continuous regulation of pressure, temperature, flow, liquid level and other processing parameters. It's an important part of automatic adjusting system, widely used in power, metallurgy, chemical, light industry, food and other automatic control systems.
Electric sleeve control valve is with larger flow coefficient, large allowed pressure difference, good stability, large opening of guide structure, not easy to vibrate when work, strong adaptability, easy to install or uninstall.
