1. Product Overview ã??ã?? The electric single-seat regulating valve is composed of a valve body, a valve seat, a valve stem, a guide sleeve, a valve cover and a sealing filler and an electric actuator. The electric single-seat regulating valve has a S-type fluid passage, small pressure drop loss, large flow, high flow characteristic accuracy and wide adjustable range. It is one of the intelligent electric control valve series. The high-performance electric single-seat regulating valve is suitable for various pressure and temperature fluids and high leakage requirements. The electric actuator is an electronic integrated structure with a servo amplifier inside. Input control signal (4-20mADC or 1-5VDC) and power supply can control the valve opening to adjust the pressure, flow, liquid level, temperature and other parameters. The electric single-seat regulating valve has the characteristics of sensitive action, simple connection, large flow, small volume and high adjustment precision. The electric single-seat regulating valve is widely used in automatic control systems of electric power, metallurgy, petroleum, chemical, pharmaceutical, boiler, light industry and other industries.
