Rain Bird PRS-Dial Pressure Regulating Module

The Rain Bird PRS-Dial pressure regulating module gives you precise outlet pressure control at the valve, minimizing pressure spikes and protecting downstream sprinkler components. A visible, threaded dial makes on-site adjustments fast and repeatable, reducing setup time and water waste.

• Maintains a steady outlet pressure between 15 and 100 psi (1.04–6.9 bar) for consistent sprinkler performance.
• Reliable accuracy (manufacturer specification ±5 psi) with a waterproof, glass-filled nylon dial cartridge to prevent fogging and binding.
• Ergonomic snap-tight cover protects the adjustment dial from tampering and vandalism on exposed installs.
• Fine adjustment knob with detents allows precise changes in increments as small as 1/3 psi for sensitive systems.
• Quick field installation: PRS-Dial threads underneath the solenoid and adapter and retrofits into existing PRS-D units.
• Schrader valve port accepts a pressure-hose gauge (sold separately) for fast verification of outlet pressure.
• Commercial 3-year warranty and corrosion-resistant construction rated to 150°F (66°C).

Compatible with Rain Bird PGA, PEB, PESB, PESB-R, EFB-CP and BPES series valves. Refer to the product tech spec and flow-range chart for application limits and maximum recommended flow rates. Documents, manuals and installation guides are available on the manufacturer's product page.
