The Regulating control valve 1604707983 is the final control element in the field of industrial automation process control, which changes the process parameters including medium flow rate, pressure, temperature, liquid level and so on by Regulating the control signal output of the control unit through its power operation. Generally by the actuator and valve composition. If according to the travel characteristics, the regulating valve can be divided into straight travel and Angle travel; According to the power used by the actuator, it can be divided into pneumatic control valve, electric control valve, hydraulic control valve three kinds; According to its function and characteristics, it can be divided into linear characteristics, equal percentage characteristics and parabolic characteristics.
Regulating valve 1604707983 is suitable for air, water, steam, all kinds of corrosive media, mud, oil and other media. The English name is Control Valve. The bit number starts with FV. Regulating valve commonly used classification: pneumatic control valve, electric control valve, hydraulic control valve, self-reliant control valve.
Regulating Valve 1604707983 plays a very important role in Regulating the plant, and its production depends on the correct distribution and control of the flowing medium. These controls, whether the exchange of energy, the reduction of pressure or the simple filling of the vessel, require some final control element.
The regulator plays the role of variable resistance in the pipeline. It changes the process fluid
2) the choice of regulating valve actuator
(1) Considering the output force of the actuator no matter what type of actuator, its output force is used to overcome the effectiveness of the load (mainly refers to the effect of unbalanced force and unbalanced torque, friction, sealing force, gravity and other relevant forces). Therefore, in order to make the valve work normally, the actuator should be able to produce enough output force to overcome all kinds of resistance, to ensure a high seal and the opening of the valve.
(2) Considering the use environment requirements of the actuator, the output force of the actuator is determined, and the corresponding actuator is selected according to the use environment requirements of the process. For example, when there are explosion-proof requirements on site, pneumatic actuators should be selected, and the junction box is explosion-proof, and electric actuators can not be selected. If there is no explosion-proof requirement, both pneumatic and electric actuators can be selected, but from the perspective of energy saving, electric actuators should be selected as far as possible. For hydraulic actuators, although not as widely used as pneumatic and electric actuators, it has the characteristics of high adjustment accuracy, fast action speed and stability, so in special circumstances, in order to achieve a better adjustment effect will also be used. Finally, the reliability and economy of the actuator should be considered, and the actuator with smooth action, light weight, beautiful appearance, simple structure and convenient maintenance should be selected.
