Pilot operated pressure reducing valve

Valvesonly Europe is the largest Pilot operated pressure reducing valve manufacturer in Italy. A Pilot Operated Pressure Reducing Valve, often abbreviated as Pilot PRV, is a specialized valve designed to regulate and maintain a desired pressure level within a fluid system. It operates by automatically adjusting the flow of fluid to stabilize pressure at a set point, even in the face of fluctuating upstream pressure conditions.

It comprises two main components: the main valve and the pilot control system. The pilot system continuously monitors the downstream pressure and modulates the main valve to adjust the flow rate accordingly. When the downstream pressure deviates from the desired setpoint, the pilot system sends signals to the main valve, prompting it to open or close to maintain the specified pressure level. This dynamic regulation ensures that downstream equipment receives a consistent and controlled flow, safeguarding against overpressure scenarios.


  • Precision Control: offer precise control over pressure levels, ensuring stability and reliability in fluid systems.
  • Wide Pressure Range: These valves can operate across a wide range of pressures, making them versatile for diverse industrial applications.
  • Self-Actuating: are designed to be self-actuating, responding automatically to changes in downstream pressure without the need for external intervention.
  • High Durability: Constructed from robust materials such as stainless steel or bronze, it exhibit high durability and longevity, even in harsh operating conditions.
  • Adjustable Setpoint: can be easily adjusted to accommodate varying operational requirements, offering flexibility and customization.


  • Equipment Protection: By maintaining optimal pressure levels,it protect downstream equipment from damage caused by overpressure, extending their lifespan and minimizing maintenance costs.
  • Energy Efficiency: By regulating pressure effectively, optimize energy usage within fluid systems, reducing operational costs and environmental impact.
  • Enhanced Safety:it ensures safe operating conditions, mitigating the risk of accidents or system failures due to pressure fluctuations.
  • Process Stability: fluid processes remain stable and consistent, promoting smooth operation and superior product quality.

Pilot operated pressure reducing valve manufacturer in Italy play a crucial role in maintaining optimal pressure levels, preventing damage to equipment, and ensuring consistent performance across various industrial applications.
