Pressure regulation is the process of controlling the pressure of gases or liquids within a system to ensure safe and efficient operation. This is commonly achieved using devices like pressure regulators, which automatically adjust the flow of a substance to maintain a desired pressure level. In various applications, such as gas distribution systems or hydraulic machinery, maintaining the correct pressure is crucial. Too much pressure can lead to equipment failure or safety hazards, while too little can result in inefficient performance. Proper pressure regulation helps optimize system functionality and prolongs the lifespan of equipment.
