What Are 3 Functional Elements of the Pressure Regulators?

functional elements of the pressure regulators

Pressure regulation is compulsory for all the media flowing through the pipes. These valves include pressure balancing, reducing and providing safety to the system and the environment. Low pressure electronic regulators provide efficient operating and automatic responses to maintain constant pressure. They react to changes and provide signaling or direct control over the process. These small pressure regulators are used with filters that are placed before the regulators to protect them from dirt particles. Because these particles can affect their operations.

Common Media types:

The most common media types that we use are:

  • Fuel and oil.
  • Air.
  • Hydraulic fluids.
  • Liquid.
  • Steam.

Below we have listed 3 functional elements of an electronic low-pressure regulator:

Loading Mechanism:

This is the first functional element of the low-pressure electronic regulator. It provides the ability for the operator to set the forces that define the outlet power pressure of the regulator. This element also provides a force that passes through the sensor and control elements.

The loading mechanism is further divided into four categories such as the spring load, dome load, air load and spring or dome combinations. All of these types have their own advantages and disadvantages.  

Sensing Element:

A sensing element is the most vital part of the low-pressure electronic regulator. This sensor senses any changes in the downstream pressure of the regulator and adjusts the pressure to the desired output. When the gas or liquid passes through the sensor then it detects the fluctuation and informs that the flow rate needs to be adjusted.

Basically, this is a physical link between the loading and the control element. It has three types: diaphragm, piston, and bellows. The diaphragm is the most expensive and good for use. Because of its simple design and enough sensitivity, it’s perfect for small applications.  

Control Element:

The last element of a low-pressure electronic regulator is the control element that performs the actual work. This element takes the high inlet pressure and decreases it down to the lower outlet pressure. Further, the sensing element sends this piece of information so that the controller knows what action should be performed to maintain the flow rate.

The media pressure is decreased by taking the high pressure from the tank and passing it through a size-changing orifice. The valve of the low air pressure regulator moves toward or away to obtain the desired pressure. 

All of these elements work together in a low-pressure controller to reduce and maintain a constant desired pressure in systems. If the value of one element changes, then this change updates the value of other elements to maintain the desired pressure.

Final Words:

Remember that too much pressure can cause the pipes to burst which is a dangerous thing. There are various regulators available in the market. But by using a low-pressure electronic regulator you can reduce and maintain a constant pressure. This regulator works on precise sensors and mechanisms to provide the desired output pressure.
