Key Features and Functions
Maintains System Pressure
Protects upstream equipment such as pumps and metering devices by preventing cavitation, flow instability, or backflow caused by excessively low downstream pressure.
Relief for Pressure Vessels
Serves as a form of safety valve, providing overpressure protection for low-pressure vessels or systems.
Creates Flow Resistance
Ensures sufficient flow resistance in gravityfed or multibranch systems to achieve balanced distribution across all branches.
Prevents Siphoning
When installed in an outlet line, it prevents liquid from being drained due to siphoning effects.
| Feature | Back-Pressure Valve | Pressure Reducing Valve |
| Senses Pressure At | Inlet (Upstream) Pressure | Outlet (Downstream) Pressure |
| Primary Function | Maintains/Restricts upstream pressure not below the set point. | Reduces/Restricts downstream pressure not above the set point. |
| Typical Installation | Installed at the end of a line or downstream of the protected equipment. | Installed upstream of the protected equipment. |
| Simple Analogy | A "brake" or pressure maintainer for the upstream side. | A "throttle" or pressure reducer for the downstream side. |
