PRV vs. BPV: Key Differences
Feature | Pressure Reducing Valve (PRV) | Back Pressure Valve (BPV) |
---|---|---|
Function | Lowers high pressure to a stable level | Maintains upstream pressure & prevents backflow |
Operation | Adjusts valve opening based on downstream pressure | Opens when upstream pressure is met, closes to prevent reverse flow |
Flow Direction | Allows bidirectional flow in some cases | Unidirectional flow only |
Installation | Installed on high-pressure pipelines | Installed on pump discharge or sensitive equipment |
Ideal for | Ensuring stable downstream pressure | Preventing backflow and stabilizing dosing systems |
How to Choose Between PRVs and BPVs?
✅ Use a PRV if you need to reduce and stabilize pressure in a pipeline.
✅ Use a BPV if you need to prevent backflow and maintain upstream pressure.
Both valves are essential for efficient flow control in water treatment, chemical processing, power plants, and industrial systems. Selecting the right valve improves system safety, performance, and longevity.
