Working Principle Electronic Pressure Regulators

The fastest-growing type of regulator has been the electronic pressure regulators that use the two high-speed solenoid valves to increase or decrease pressure in the past few years. The reason for it is its automatic control that helps you to manage the pressure automatically. You don’t need to manually operate the regulators with the digital pressure regulators when the fluid pressure is too low or high. In this guidepost, you will know about the working of the electronic pressure controllers.

What are Electronic Pressure Regulators:

The digital pressure regulator is said to be a valve that can cut off the flow of fluid when they reach a certain pressure automatically. In this process industry, the electronic pressure controller allows the high pressure of the fluids to be reduced usable & safe pressure for different applications.

What are the Main Uses of a Pressure Regulator?

As you know, the use of electronic pressure regulators is common in many different industries. In the business application, the main reason for its use in the process industry is safety when you’re dealing with high or low pressures. Many applications make use of dangerous liquids or gases. Therefore, it is very important to manage the flow or pressure of the fluids to avoid leakage or explosion. The best approach is to use electronic pressure regulators that can conveniently deal with fluid pressure.  

How Electronic Pressure Regulators work:

The electronic pressure regulators use a push valve & vent valve to maintain the outlet pressure to the desired set point. The internal pressure sensor of the electric air pressure regulator monitors the output pressure. The basic function of the analog & digital controller is that it adjusts the timing of the valve to maintain the set-point. Usually, they need a DC power supply & a signal set point. The analog type of pressure regulator accepts the current of 4-20 mA or voltage of 0-10 or 0-5 VDC as input. The digital circuits of the electronic pressure control regulator accept the serial communications in addition to the common analog standards. Most of the models of pressure regulators provide the feedback signal informing the sensor valve for the pressure. 

There are many critical parameters for the application of the air pressure regulator. The orifices used in the valves come in different sizes that should match the flow rate of the fluid as required. The volume of the fluid space can impact the tuning of the valves. A few of the electronic pressure regulators provide a volume less than the approximation of one liter, which causes issues like frequent & unnecessary valve action. While some of the models use the small bleed valve that is suitable for no-flow or low-flow applications. 

Applications For Electronic Pressure Regulator:

There are numerous applications of electronic pressure regulators. This is because this technology is the best way to manage the close lop pressure control. Below listed are some of the common applications of pressure control valves. 

  1. Direct control of pressurized air & inert gases.
  2. Operation of small-bore cylinders
  3. Medical and analytical applications
  4. Leak testing
  5. Packaging
