Choosing the Right PRV
Here's what to consider when selecting a PRV:
Understanding Pressure Requirements: Know your 
system's normal pressure and potential spikes. The PRV 
needs to handle both effectively. Also, determine the 
ideal pressure for your equipment.

Valve Selection
● Flow Rate: Size the PRV based on flow rate, not just pipe 
size. An oversized PRV can be noisy and damage itself. 
Aim for a flow rate between 1-2 m/sec (check 
manufacturer's charts).
● Pressure Range: The PRV's pressure range should 
handle both your inlet pressure and desired downstream 
pressure. The valve's maximum pressure rating must 
exceed your system's maximum pressure.
Valve Types
● Pilot-operated PRVs (most common): Precise control using a 
pilot line to sense downstream pressure and adjust the main 
valve.
● Self-contained PRVs: Simpler design that regulates pressure 
directly without a separate pilot line (less precise).
● Pressure Relief Valves: Not technically PRVs, but release 
excess pressure beyond a set point for added safety (consider 
using them with PRVs).

Additional 
Considerations
○ Bypass: For fluctuating flow rates, consider a PRV with a 
bypass for low flow to prevent wear on the main PRV.
○ Ease of Installation and Maintenance: Consider 
accessibility, connection types, and availability of replacement 
parts for long-term system performance.
○ Standards and Regulations: Ensure the PRV complies with 
relevant standards for safety and code adherence.
Conclusion
Choosing the right Pressure Reducing Valve safeguards 
your system and equipment. By considering these factors 
and potentially consulting a professional, you can ensure 
optimal performance, safety, and longevity.
