How DRV Enhances System Control: Key Benefits and Applications
Understanding DRVs in Modern Building Systems DRV Valve What is a DRV, and how does it function? A differential pressure control valve (DRV) maintains a constant pressure difference across a branch or terminal unit in hydronic systems. By stabilising pressure fluctuations caused by load changes or pump speed variations, it ensures consistent flow and supports reliable heating and cooling performance. DRVs operate using a spring-loaded diaphragm or piston that automatically adjusts to maintain the preset pressure differential. This removes the need for continuous manual adjustment and keeps systems stable as demand changes. Modern DRV are compact, easy to install, and often include measurement ports for simplified commissioning and diagnostics. Their automatic balancing capability makes them ideal for energy-efficient building designs. Why system control matters in hydronic networks Precise control is essential for efficient hydronic system performance. Poor control ca...
