Pressure regulators are common in home and industrial applications. For example, an electronic vacuum regulator is used on gas stoves to control propane. In home heating furnaces to control natural gas in medical and dental devices to control oxygen and gas anesthesia in an automated system that uses air to control compressed air in the engine to control fuel and in fuel cells to control the hydrogen. In this article, you will read about the major applications of vacuum regulators along with its working and material used in it that helps to manage the pressure of the fluids.

Major Applications of Electronic Vacuum Regulator

Application of Electronic Vacuum Regulators:

There are numerous applications of electronic vacuum regulator in which the process vessel requires to be managed under vacuum controlling conditions. It includes examples of vacuum distillation, vacuum extraction, vacuum dying, etc. The equilibar electric vacuum regulators use the 1:1 setpoint pilot pressure instead of using the spring on their dome or providing improved precision. The feature of dome-loaded allows easy computer automation by the addition of a separate regulator, which is calibrated for the range of vacuum.

The electronic vacuum regulators are very useful in a wide range of applications industrially & domestically. Below are listed the most common applications of vacuum controllers.

  • Dairy milking machinery
  • HVAC equipment
  • Laboratory and analytical instruments
  • Industrial liquid flow optimization
  • Altitude simulations
  • Airflow control
  • Pressure stabilization
  • Pump control
  • Flowmeters
  • Medical and dental equipment
  • Food product packaging
  • Reservoir regulation
  • Fuel cell efficiency

The precise application of the vacuum controller will help you in regulating the pressure of the fluids without the requirement of manual flow control. It greatly reduces energy and labor costs and increases the system’s overall efficiency.

How Does the Electronic Vacuum Pressure Regulator Works:

The electronic vacuum regulator is pressure controlled with inlet and outlet ports that allow high-pressure air to flow into or out of the system. If necessary, the air pressure outside the digital vacuum regulator is less than the air pressure sucked into the vacuum pump. When the process reaches the vacuum pressure setting The vacuum regulator switches off and stops excess current from the vacuum supply line. If the system’s pressure is too high, the valve opens and allows air to flow through it. The vacuum circuit breaker is another vacuum regulating device that will be discussed later. And the regulators work according to the same principle; the main difference is that the regulator does not allow air to enter the line of the system and the breaker.

The vacuum pressure regulator valve should be near or directly on the vacuum storage tank. It must be sensitive to be able to withstand rapid reactions to vacuum changes. The absolute pressure in the vacuum is not lower than zero, so it must be adjusted. It can be adjusted with a vacuum regulator that is more efficient than a conventional single valve seat. The electronic vacuum regulator valve has a diaphragm spring mechanism that controls airflow through the pump or outside air to better manage internal pressure. The adjustable vacuum controller ensures the operator is always operating at maximum pressure without the need for frequent manual operations.

The material Used in the Digital Vacuum Regulator:

A wide range of materials is available to handle a wide range of fluids and working environments. Typical driver component materials include brass, plastic, and aluminum. Various grades of stainless steel (eg, 303, 304, and 316) are also available. The spring used inside the electronic vacuum regulator valve is usually made of steel wire. (carbon steel) or stainless steel

Brass is suitable for most general applications and is usually inexpensive. Aluminum is often specified when considering weight. Plastic is important when it comes to low-cost or disposable items. Stainless steel is often used for corrosive liquids. Use in corrosive environments when considering fluid cleanliness or when operating temperature is high

Another common thing is the compatibility of the seal material with the fluid and the operating temperature range of the vacuum pressure regulator valve. Buna-n is a common sealant. Some manufacturers offer auxiliary seals, including fluorocarbon, EPDM, silicone, and perfluoroelastomer.

Fluid chemistry must be considered before deciding on the best material for your application. Each liquid has its own characteristics. Therefore, care must be taken to choose the correct body and seal material that will come into contact with the liquid. Controls that come into contact with liquids are called “wet” components.


The material chosen for the electronic vacuum regulator must not only be compatible with the fluid. It must also function properly at the expected operating temperature. The main concern is whether the selected elastomer will perform correctly in the expected temperature range. Additionally, operating temperature may affect flow capacity and/or spring rate in use. hard work

Work Pressure:

Inlet and outlet pressure are important factors to consider before choosing the best electronic vacuum regulator. The key question to answer is what is the range of input voltage fluctuations? What is the required outlet pressure? What is the allowable variation of outlet pressure?

Flow Specification:

What is the maximum flow rate required by the application? How different is the flow? Handling requirements are also an important consideration.

Size and Weight:

In many high tech applications space is limited and weight is a factor Some manufacturers specialize in smaller components and should be consulted. selection of materials especially the components of the vacuum pressure controller will affect weight Consider port (thread) size, configuration style affect the size and weight.

Final Words:

No doubt, there are multiple applications of electronic vacuum regulator where the process vessel is required to be maintained under the vacuum control conditions when there are different set points. It includes examples of vacuum distillation, vacuum extraction of essential oils & flavors, and vacuum drying. In this article, we discuss various applications of digital vacuum regulators for managing or controlling the pressure of air. We also mention how these vacuum controllers work along with the material used in its manufacturing. We hope that this guidepost was a good piece of information for you.
