Information about Electronically Controlled Pressure Regulator

Electronically controlled pressure regulator tools are being used widely in different industries but still many people are unfamiliar with the working of these brilliant tools. First most know that electronic pressure regulator devices are actually used to lower down the pressure in a pneumatic system. The second basic purpose of these regulators is to maintain the outlet pressure from the valve at a set value which is quite impossible if you try to do it manually. There are different kinds of pressure regulator available in the market used for different purposes. Some of these include:

  • Back pressure reducers
  • Vacuum Pressure 
  • Differential pressure 
  • Pressure and flow reducer for oil, gas, fuel and other fluids

Whenever you are choosing an electronically controlled pressure regulator you have to make sure that you consider their pressure controlling capabilities and regulation range. The common media types that an electronic pneumatic regulator can control include air, fuel, oil, water, steam, hydraulic fluids and other abrasive or corrosive fluids.

Function of the Electronically Controlled Pressure Regulator

Modern control pressure regulator has a simple function. The regulators reduce high pressure on the indie of the valve to stabilize the output pressure. There are dozens of applications where the internal pressure in a pneumatic system isn’t going to be stable where these devices come to the rescue. These regulators can surely regulate pressure but you should know that they are likely to experience droop. Droop for your knowledge is the sudden drop in pressure. An important thing to note is that pressure regulators only maintain the pressure of the medium and not their flow. The delivery pressure is maintained. 

Operating components of the Pressure Regulators

There are three basic operating components in the electronically controlled pressure regulator. Here we have discussed them in somewhat detail.

Loading mechanism 

The loading mechanism in the pressure regulators is going to affect the setting of the regulator and the delivery pressure. The regulators use spring designs for pressure regulation. When the knob is turned the pressure is adjusted accordingly. Turning the knob anti clock wise would increase the pressure and vice versa. 

Sensing element 

In the electronically controlled pressure regulator you are going to see sensing elements. These elements basically react to the force that is placed on the loading mechanism. They also set a difference between the inner and outer pressure. Modern devices like the electronic water pressure regulator devices use a diaphragm to act as an accurate sensing element. These are commonly made of metals or elastomers depending on the use of the regulator. 

Control element

The control element is the proportional air valves  that is responsible for the reduction of inlet pressure with respect to the set outer pressure by the operator. The control element works according to the instructions or feedback given by the electric signals set by the user. When the operator compresses the loading mechanism at a set pressure valve, the sensing element would experience a change in force which as a result would change the force on the control elements in the electronically controlled pressure regulator.
