PR – Pressure-reducing Valve

The PR – Pressure-reducing Valve ensures stable downstream pressure and prevents over-pressurization, pipe damage, water hammer, and uneven flow distribution. Maintaining a steady, predetermined pressure downstream, the valve opens fully if pressure falls below the set level, minimizing losses and ensuring efficient system performance.
Note: Modulated operation may cause cavitation under certain conditions. Consider using DOROT S300+ 30F anti-cavitation valve, or two valves in series.
