Unox DN 100 Pneumatic Proportional Control Valve with 2 Way Positioners

What is 2 way pneumatic proportional control valve? 2 way pneumatic proportional control valve, a kind of control valve, is the valve used to control the fluid by changing the size of the flow passage in the direction of the signal from the controller. Pneumatic proportional control valve enables pressure, temperature, flow rate and level control in all the processes where fluid is located. Control valves are used in enterprises to control the cold water, hot water, steam, hot water, steam and gas, etc. produced by consuming energy. Ensures that fluids 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 set point 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 keep a process variable at a specified setpoint or within a specified range. In the proportional control system, the control signal is generated by a controller that compares the set point and the process value and calculates the error. The controller then applies a control signal proportional to the error over the course of the The control signal is generally implemented through a control element, such as a valve, which can adjust the flow of a fluid or the position of an mechanism to change the process variable.
