There is no doubt that industrial processes need industrial glasses for different operations depending on the gas distribution systems. It is because to deliver the gas from its actual source safely. Hoses, cylinders, gauges, and other components that use the gas distribution systems, electronically controlled pressure regulator device plays an essential role in maintaining the high pressure of gasses. Understanding how the electronic pressure controllers work is necessary for those new to the operations or managing the gas distribution system.
How Do Gas Pressure Controllers Work:
In a general & simple explanation, the air pressure controllers are used to reduce the incoming pressure of gas or fluids to the lower outgoing pressure. Not only this, but these electronically controlled pressure regulator devices also maintain the pressure you set whenever the gas pressure is low or high. The airflow regulator has three essential elements, which contains this process:
- Loading elements such as the spring.
- Piston or diaphragm type sensing element
- Controlling element, which can be poppet or spring-loaded valve.
Interaction Between the Elements:
The interaction between the elements we mentioned earlier develops and maintains the pressure in the below-mentioned ways.
- The proportional air valve opens by the created force of the spring, which allows the gas to pass through the air regulator.
- After it, the gas pressure in between the outlet & point of use builds at a level. Then, it applies the pressure to the sensing element so that it starts closing the valve of the electronically controlled pressure regulator. It closes the valve until the point where it remains sufficiently open for managing the set pressure.
This is how these three elements work in the electronic air regulator.
The Flow Curve & Operating Range:
All the electronically controlled pressure regulator devices must have a flow curve, which defines the operation range of electronic pressure control valves. The use of a flow curve is important in finding the valuable capacity of regulating.
Seat-Load Drop or Lockup:
The lockup of the electronic pressure regulators indicates that the pressure above the point you set is needed to completely close the valve and also to prevent the flow of gas. It is only in a particular situation when the high pressure makes the electronically controlled pressure regulator close the poppet.
- The ideal range is known to be the area, which is below the flow curve the air pressure controller provides the greatest control.
- Choked flow is considered to be the limiting condition where the reduction in the downstream pressure doesn’t have any impact on its flow rate for the fixed pressure & temperature. In this situation, the electronically controlled pressure regulator valve is completely opened. So that there is no longer any regulating pressure for the gas.
The accuracy of the pressure regulator can be found by plotting the outlet pressure against the rate of gas flow. As the rate of flow rises, the outgoing pressure drops down. This relationship is known as droop.
In this post, we mention how the electronically controlled pressure regulator works in industrial processes. We also took into account the three essential elements of the pressure controllers that manage the pressure.
