Motorized globe control valve

Overview of Motorized globe control valve

Motorized globe control valve is an important executive unit instrument in industrial automation process control. With the increasing degree of automation in the industrial field, it is being more and more used in various industrial production fields. Compared with the traditional pneumatic control valve, it has obvious advantages: the electric control valve saves energy (only consumes electric energy when working), is environment-friendly (no carbon emission), and is installed quickly and conveniently (without complex pneumatic pipeline and air pump workstation). According to the power used by its actuator and its function and characteristics, the valve is divided into linear characteristics, equal percentage characteristics and parabolic characteristics

Use and maintenance of Motorized globe control valve

With the rapid development of China's industry, Motorized globe control valve is more and more widely used in metallurgy, petrochemical and other fields, and its stability and reliability are becoming more and more important. Its working state will directly affect the automatic control process. This paper will elaborate on the use and maintenance of electric control valve in detail. It is widely used to accurately control the process parameters of gas, liquid, steam and other media, such as pressure, flow Keep the temperature, liquid level and other parameters at the given value

TheMotorized globe control valve is composed of a straight stroke all electronic electric actuator and a top guide straight through low flow resistance single seat valve. It has compact structure, light weight, sensitive action, s-streamline fluid channel, small pressure drop loss, large valve capacity and accurate flow characteristics. It can directly accept the control signals input by the regulating instrument (4-20mA DC, 0-10mA DC or 1-5V DC) and single-phase power supply to control the operation, so as to realize the automatic regulation and control of the fluid medium in the process pipeline. 

Precautions for installation of Motorized globe control valve

(1) The control control device is a field instrument. The normal temperature is required to be in the number of -25 to 60 °C, and the comparative humidity is less than or corresponding to 95%. If it is installed in the open air or stuck in a job high temperature place, water-proof and cooling actions should be obtained. Steer clear of vibration resources or add anti-vibration measures where there are vibration resources.

(2) The Motorized globe control valve should be installed vertically generally speaking, and can be installed obliquely in special cases. When the inclination viewpoint is too large and also the valve weight is actually large, a bracket should be included with protect the valve.

(3) Typically, the pipeline for installing the controlling valve should not be too high from the start or the surface. Once the height of the pipeline is more than 2m, the platform should be set up whenever you can to facilitate the procedure and maintenance of the handwheel.

(4) Before setting up the regulating control device, the pipeline should be cleaned to remove dirt and welding slag. Right after installation, so as to ensure that no impurities stay in the valve body, the valve should be cleaned again, that is, when the medium is released, all valves should be opened to prevent impurities from getting stuck. Right after using the handwheel mechanism, it should go back to the original neutral position.

(5) In order to continue the creation process in the instance of disappointment or repair of the control control device, the control control device shall be outfitted with a circumvent line.
