Electronic Integrated Control Valve
Structural features of electric control valve
1. The servo amplifier adopts deep dynamic negative feedback, which can improve the accuracy of automatic adjustment.
2. Electric operators come in various forms and are suitable for 4~20mA. DC or 0~10mA.DC.
3. The adjustable range is large, the inherent adjustable ratio is 50, and the flow characteristics include straight line and equal percentage.
4. The electronic electric control valve can directly control the valve opening by current signals without the need for a servo amplifier.
5. The valve body is designed according to the principle of fluid mechanics with a low-flow resistance passage of equal cross-section, and the rated flow coefficient is increased by 30%.

Regulating valve, also known as control valve, is a device that uses power operation to change fluid flow in a process system. The International Electrotechnical Commission (IEC) defines the regulating valve [called Control Valve abroad] as: "It includes a net component, an internal valve body component that changes the flow rate of the process fluid, and one or more actuators. connected. The actuator is used to respond to the signal sent by the control component. The regulating valve is composed of an actuator and a valve component. The actuator is the driving device of the regulating valve. It generates corresponding thrust according to the signal pressure, causing the push rod to move periodically, thereby driving the valve core of the regulating valve to move. The valve component is the regulating part of the regulating valve. It directly interacts with the medium through the displacement of the actuator push rod to change the throttling area of the regulating valve to achieve the purpose of regulation. Regulating valves are mainly divided into pneumatic regulating valves, electric regulating valves and hydraulic regulating valves according to their energy sources. The difference lies in the actuator they are equipped with. The pneumatic control valve uses compressed air as the power source and is equipped with a pneumatic actuator. The electric control valve uses electricity as the power source and is equipped with an electric actuator; the hydraulic control valve uses hydraulic pressure as the power source and is equipped with a hydraulic actuator. According to needs, the regulating valve can be equipped with a variety of accessories to make it more convenient to use and more complete in function. These accessories include valve positioners, handwheel mechanisms, electrical converters, etc.
