In a fluid system, maintaining constant flow and pressure within a safe limit is of utmost importance. Pumps and compressors generate pulsations, leading to pressure fluctuations that require rapid control for precise fluid system operations. However, traditional manual regulators fall short in terms of responsiveness compared to the latest electronic regulators. Ensuring accuracy is essential for every process to function correctly. Temperature fluctuations, changes in concentration, and moisture levels can arise as a result, compromising process accuracy and potentially causing damage.

Key concepts in fluid system design:

  • Constant flow and pressure: Fluid systems rely on maintaining a consistent flow rate and pressure level to ensure optimal performance and safety.
  • Pressure fluctuations: Pulsations generated by pumps and compressors introduce pressure variations that must be controlled promptly to prevent disruption and inaccuracies.
  • Rapid response: Electronic regulators excel in their ability to quickly and precisely respond to pressure fluctuations, enabling accurate and efficient fluid system operations.
  • Accuracy and precision: Achieving accurate results in fluid processes is crucial, as variations in temperature, concentration, and moisture levels can affect process integrity and lead to undesirable outcomes.
  • Damage prevention: By employing electronic regulators, the risk of damage to the system and its components is reduced, thanks to their ability to maintain stable pressure levels and prevent sudden spikes.
  • Process optimisation: Electronic regulators offer enhanced control and feedback mechanisms, enabling users to fine-tune pressure settings and ensure consistent performance for improved productivity and efficiency.

Remember, the bulleted list has been provided to highlight the key concepts related to fluid system design and the advantages of electronic pressure regulators.


In high-tech applications and systems, manual adjustment of mechanical pressure regulators presents limitations. However, the use of electronic pressure regulators, equipped with microcontrollers or programmable logic controllers (PLCs), unlocks precise control over output pressure. 

By incorporating a pressure transducer, a closed-loop control system is established, allowing feedback voltage to serve as a signal for accurate pressure management. The control element of the digital pressure regulator receives this signal and provides instructions to the load element, facilitating real-time adjustments to maintain consistent pressure levels within the fluid system. This enhanced consistency ensures reliable and stable performance.

Control Over Pressure

Electronic pressure regulators offer several advantages in terms of controlling pressure within a system. These regulators provide superior repeatability, high resolution, and quick response times when compared to their counterparts. By utilising electronic operation, the need for manual pressure checks is eliminated.

Electronic pressure regulators excel at maintaining the user-defined pressure value, preventing it from exceeding the set limit. This is achieved through the implementation of vent and push valves, which play a pivotal role in this functionality. These valves automatically adjust the passage of the fluid within the regulator based on instructions received from the control element. As a result, the required pressure is efficiently maintained, ensuring optimal system performance.

With electronic pressure regulators, users can rely on precise pressure control, eliminating the risk of pressure deviations and facilitating accurate and consistent operations. The automated functionality of these regulators enhances efficiency and frees operators from the need for constant monitoring and adjustment of pressure metres.


An electronic pressure regulator provides way better safety than a mechanical device. It does not require the operator to go near the regulator and loosen or tighten the screw to maintain the required value of pressure so that the system can operate efficiently and deliver optimal results. The user just has to send a value of pressure to the electric pressure regulator and it automatically reduces the incoming pressure and makes it equal to the set value of the pressure.
