Piloted Pressure Reducing Control Valve
The piloted pressure reducing valve maintains a constant downstream pressure, regardless of variations in inlet pressure or flow rate. Its external pilot design allows for precise control, stable response, and minimal head loss.
- Reduces and maintains downstream pressure in a hydraulic system.
- Automatic piloted operation: control is achieved by a hydraulic pilot that adjusts the diaphragm opening according to the set pressure.
- Ductile iron body with anti-corrosive internal coatings for long service life.
- Suitable for potable water, irrigation, pumping systems, and industrial networks.

Applications
Potable Water Networks: Reduces high pressure from the main network to a safe and constant level in supply areas. This is essential in areas with variable topography or tall buildings where pressure variations are frequent.
Irrigation Systems: Ensures that secondary lines and sprinklers receive optimal and uniform pressure. Thanks to its automatic operation, it maintains stable conditions without manual intervention. For this reason, it is widely used in agricultural and industrial irrigation systems.
Industrial Process Control Systems: Provides stable working pressure for operating equipment and instruments sensitive to fluctuations. Therefore, it is frequently specified in plants where pressure variability affects process quality. In particular, it stands out in dosing and flow control applications.
Steam Systems: Reduces steam pressure before its use in boilers, heat exchangers, and turbines. Likewise, its precise control contributes to the correct temperature management in these systems, thereby protecting equipment from overpressure.
Fire Protection Systems: Reduces high pressure from the source to a controlled and safe discharge pressure for sprinkler networks and hoses. Consequently, it guarantees the correct operation of the system in case of emergency.
General Hydraulic Systems: Automatically modulates pressure using the line pressure itself. This way, it does not require external power sources. Ultimately, it is the most economical and reliable solution for pressure control in hydraulic systems of any scale.
