Differential Pressure Regulating Valve Watts USVR Anti-noise

🚀 Pressure Stability and Noise Elimination in Heating Circuits

The Watts USVR Differential Pressure Regulating Valve It is a highly engineered component designed to maintain a constant head (pressure) in heating systems that use variable flow circulation pumps. Its primary function is balance the overloads generated by the reduction in flow, preventing excessive pressure increases and eliminating the annoying noises in thermostatic valves and radiators.

Made with a body of cast bronze and a large internal dock made of special steel, the USVR offers a silent dynamic construction and high precision in adjustment, guaranteeing the optimal performance of gas boilers that require a minimum circulation flow.

✨ EEAT and Benefits: Guaranteed Control and Silence

Installing the Watts USVR demonstrates Experience in hydraulic design, ensuring an efficient, quiet and safe system, which generates high Trust.

• Effective Noise Elimination: It controls the pump's retention height, preventing overpressures that cause hydraulic noise in the system's terminal elements.
• System Protection: It ensures a minimum amount of circulating water, protecting gas boilers against overheating and flow fluctuations.
• Simple and Precise Adjustment: It incorporates a visible adjustment scale (of 50 mbar to 500 mbar) which eliminates the need for complex diagrams for on-site configuration.
• Quality Construction: Body in cast bronze long-lasting and central shaft with hydraulic damping for low friction and dynamic and quiet operation.
• Convenient Factory Preset: It comes configured as standard to 200 mbar, a suitable value for most installations.

❓ Frequently Asked Questions (FAQ) Technical

💡 Why is hydraulic damping important in this valve?

The hydraulic damping of the central shaft is key to quiet operation.It reduces friction and the disc's reaction speed to small pressure changes, preventing "water hammer" and noisy oscillations, especially when the pump flow rate varies rapidly.

💡 What does it mean for the valve to adjust "within a proportional band"?

This means the valve is not an "on or off" 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 smooth and, therefore, quiet regulation.

💡 The factory setting of 200 mbar Is it always suitable for systems with variable speed pumps?

For many standard domestic heating systems, this is a good starting point. However, in systems with high-efficiency pumps with very high heads or with large differences in circuit pressure loss, it is recommended to adjust it to the exact design value (desired retention height) to maximize efficiency and quiet operation.
