What is a 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 ensure that fluids such as cold water, hot water, steam, superheated water, steam and gas, etc., which are produced by expending energy in enterprises, can be transported and controlled without any loss.

What is the Proportional Working Principle?

The principle of proportional operation 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 in proportion to the size and direction of the error. This type of control system is used in a variety of applications where it is necessary to maintain a process variable at a specific setpoint or within a specific range.

In a 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 typically applied through a control element, such as a valve, which can adjust the flow of a fluid or the position of a mechanism to change the process variable.
