3 Common Problems Faced by the Pressure Regulator

Pressure Regulator

An electronic gas regulator allows you to control the pressure of the gas in a system. With the help of it, you can reach a required value of the pressure for performing a specific task. It consists of three main elements that are:

  • Control Element.
  • Sensing Element.
  • A Loading Element.

Although it provides accuracy, still there are chances to face the problems. Read further to know about these problems.

Common Problems:

Here we have listed 3 most common problems faced by the electro pneumatic regulators:


An electronic gas regulator enables the user to reduce and maintain a constant pressure in the system to fulfill the need. Over time, the regulator may start facing blockages because of the presence of the dust particles in the gases flowing through the system. These dust particles accumulate inside the precision air regulator and restrict the passage.

An effective cleaning of the valve makes sense to resolve this issue. One can easily do that  by just soaking the valve of the regulator in a calcium and lime remover. After rinsing, assemble it again at its place and get the expected results. 

Damaged Internal Components:

Most of the electronic pressure regulators contain a heat resistant diagram attached to a spring. When the fluid pushes the diaphragm with a high force then the valve closes tightly. In contrast, the low pressure lets the diaphragm remain in the relaxed state while keeping the valve open widely. With the passage of time the moving parts of the proportional pressure regulator bear a significant amount of pressure which makes them weak. The performance of these components start going down slowly and they become less responsive. 

Generally, the lifespan of an electronic gas regulator is approximately between 7-12 years. If you are facing any fluctuations in the pressure after installing the pressure regulator, then it may happen because of the failure of any of the internal components. Meanwhile, the older a valve gets the more it becomes prone to failure. To solve this problem you can repair the regulator. This strategy may end up costing more time and effort than replacing the valve. So for that reason, you should replace the whole valve. 

Incorrect pressure Settings:

The most common problem is the incorrect setting of the pressure. If you are not getting the accurate pressure from the digital pressure regulator, then don’t think immediately that the regulator is broken or failed to provide the desired pressure. In this kind of situation, you are required to adjust the position of the valve properly. Basically, all the electronic gas regulators have a pre-set value of the pressure of 50 PSI. A professional or experienced person can help you to resolve this issue. By adjusting the pressure and the position of the valve accurately you can obtain the required pressure.

Final Words:

An electronic gas regulator not only allows you to reduce the pressure but also ensures the safety of the system. But with the passage of time, its performance goes down. A regularly scheduled checking of the operations is the everything that’s necessary to keep things running fluently.
