What is 2 Way Pneumatic Proportional Control Valve?
2-Way Pneumatic Proportional Control valve, which is a type of control valve; It is a valve used to control the fluid by changing the size of the flow passage as directed by a signal from a controller. Pneumatic proportional control valve provides pressure, temperature, flow and level control in all processes where fluid is present. Control valves are used for cold water, hot water, steam, superheated water, steam and gas etc. produced by consuming energy in enterprises. It ensures that the fluids can be transported and controlled without any loss.
What is Proportional Working Principle?
The proportional operating principle is a control system concept that refers to the use of a control signal that is directly proportional to the error between the desired setpoint and the actual process value. In other words, the control signal is adjusted proportionally to the size and direction of the error. This type of control system is used in various applications where it is necessary to keep a process variable at a certain setpoint or within a certain range.
In the proportional control system, the control signal is generated by a controller that compares the setpoint with the process value and calculates the error. The controller then applies a control signal proportional to the error to the process. The control signal is generally applied via a control element such as a valve that can adjust the flow of a fluid or the position of a mechanism to change the process variable.
