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. Call us: +91 9099477256 / Website: www.airaindia.com Email us :

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.
