The use environment and precautions of explosion-proof electric control valve
Explosion-proof electric regulating valve is an important execution unit instrument in industrial automation process control. With the increasing degree of automation in the industrial field, it is being used more and more in various industrial production fields. The valve is divided into three types: linear characteristic, equal percentage characteristic and parabolic characteristic according to … -
Summary of common problems of regulating valve and selection principle of regulating valve
The regulating valve, also known as the control valve, changes the fluid flow by means of power operation by receiving the control signal output by the regulating control unit. The regulating valve generally consists of an actuator and a valve. According to the power used by the actuator, the control valve can be divided into three types: pneumatic control valve, electric control valve and hydraul… -
What are the pneumatic diaphragm single-seat control valves, and how are the control valves classified?
Pneumatic membrane single-seat control valve can be divided into 5 aspects, namely according to use and function, medium working temperature, pressure, special purpose and according to principle, function and structure. Pneumatic control valve is to use compressed gas as the power source, the cylinder as the actuator, and with the help of valve positioner, converter, solenoid valve, position reten… -
Precautions for the use of pneumatic single-seat control valve
The pneumatic single-seat regulating valve is composed of a pneumatic multi-spring diaphragm actuator and a low-flow resistance single-seat valve. The new type of actuator has a low height and low weight, and is easy to install and calibrate. The new valve body has a compact structure, a smooth flow channel, and a large flow coefficient. . In order to achieve interchangeability, the pneumatic sing… -
The difference between electric control valve and pneumatic control valve
Pneumatic regulating valve is composed of pneumatic actuator and regulating valve.… -
Types and working principles of common flow control valves
Electric regulating valve is a device suitable for flow regulation in computer monitoring system. Generally used in unattended thermal stations. Electric regulating valve consists of valve body, driving mechanism and transmitter. The temperature control valve is a device for self-operated flow regulation through the temperature sensor package, and does not require an external power supply; while t… -
The control valve can also be called a full-function valve
The control valve has eight functions in total, and the eight functions of the full-function ultra-light control valve are excellent, so it is called "full-function valve".… -
Installation method and application skills of positive and negative angle control valve
The angle control valve has a simple flow path and low resistance, and is generally suitable for forward use (installation). However, in the case of high pressure drop, it is recommended to use the angle-type control valve in reverse to improve the unbalanced force and reduce the damage to the valve core, and at the same time, it is also beneficial to the flow of the medium and avoids coking and c…
