It reduces friction and the disc's reaction speed to small pressure changes, preventing \"water hammer\" and noisy oscillations, especially when the pump flow varies rapidly.\u003c\/p\u003e\n\u003ch4\u003e💡 What does it mean that the valve adjusts \"within a proportional band\"?\u003c\/h4\u003e\n\u003cp\u003eIt means that the valve is not an \"all-or-nothing\" control. Instead of closing or opening completely upon reaching a threshold, it modulates its opening gradually and proportionally to the detected pressure difference. This results in fluid and, therefore, silent regulation.\u003c\/p\u003e\n\u003ch4\u003e💡 Is the factory setting of \u003cspan class=\"math-inline\" data-math=\"200 \\, \\text{mbar}\"\u003e200 mbar\u003c\/span\u003e always suitable for systems with variable speed pumps?\u003c\/h4\u003e\n\u003cp\u003eFor many standard domestic heating systems, yes, it is a good starting point. However, in systems with very high-head high-efficiency pumps or with large differences in circuit pressure loss, it is recommended to adjust it to the exact design value (desired head) to maximize efficiency and silence.\u003c\/p\u003e\n\u003ch3\u003e📞 Technical Support and Adjustment Advice\u003c\/h3\u003e\n\u003cp\u003eIf your system presents noise or if you need to calculate the optimal differential pressure for your installation (including specific gas boilers), contact our technical support team.
