Why do we need the Electronic Pressure Regulator?

An electronic pressure regulator is a device that assists you to control the pressure of liquids or gasses by changing a high input pressure to a lower controlled output pressure throughout the medium. They also help to possess the output pressure stable even when the inlet pressure changes. 

An electric pressure regulator is commonly used in a type of residential and industrial applications. For example, to regulate propane in gas grills, oxygen in healthcare equipment, compressed air store for industrial purposes, and fuel constraint in automotive engines and aerospace applications. The electronic pressure valve might be simple on-off valves (digital) or proportional valves (analog). Pressure regulation generally flows from a higher source pressure to a lower output pressure which is a fundamental characteristic shared by all of these applications.

Why Proportional air Valves are used? 

In recent years, electronic pressure regulator has actually come into their own for different purposes. These pressure regulators offer higher pressure, more flexibility, and extra robustness compared to previous technologies. 

How do Proportional air Valves work? 

An electronic pressure regulator works by using a push valve and a vent valve to keep the outlet pressure at the selected set-point. Generally, a small internal pressure sensor observes the output pressure and a digital or analog controller adjusts the timing of the proportional valves to maintain the set-point.

These EPRs normally need a DC power supply and a set-point signal. Analog buttons commonly take either current or voltage input. Models with digital circuits can accept serial transmissions in addition to the common analog standards. Most models also suggest a feedback signal informing the pressure sensor value.

An electric air pressure regulator is several essential parameters for the successful application of this technology. The holes in these regulators come in several different sizes and should be matched according to the required flow rate. The volume of the gas space can affect the tuning of the electronic fuel pressure regulator.

For some models of the control pressure regulator, gas volumes less than approximately 1 liter can cause issues such as “humming” or regular and extreme valve action. Some models include a small bleed valve (vent a small amount of gas to the atmosphere) for very low or no flow applications. The digital pressure regulator is rated for lifetimes in the range of 25 to 150 million cycles.

Applications for an Electronic Pressure Regulator

There is an array of applications for electronic pressure valves, this is due to the particular that their main purpose is to deliver closed-loop pressure control. And this can relate to many industries and applications.

Some common applications include:

  • Direct control of pressurized air and inert gases.
  • Operation of small bore cylinders.
  • Medical/analytical applications.
  • Leak testing.
  • Packaging.
