Rain Bird PGA 1 in. Inline/Angle Irrigation Valve (100-PGA) — PVC, Flow Control & Slow-Closing

The Rain Bird PGA 1 in. inline/angle valve with flow control (model 100-PGA) is a compact, rugged PVC irrigation valve that gives reliable on/off control and adjustable flow for residential and light-commercial sprinkler systems.

This valve combines a globe or angle body with an internal flow regulator and a captured solenoid design so you can manage water delivery with fewer service visits. It accepts a latching solenoid for battery-operated controllers, supports an optional field-installed pressure-regulating module, and features slow-closing performance to reduce water hammer. Built for irrigation installers and property managers, the PGA balances durability with simple field servicing.

How does the PGA valve improve sprinkler performance?

The PGA helps maintain consistent sprinkler behavior by offering adjustable flow and optional pressure regulation at the control point. Its design filters pilot flow and limits sudden shutoff forces, which protects downstream sprinkler heads and piping from pressure spikes.

• Accepts field-installed PRSD pressure-regulating module to control upstream pressure.
• Double-filtered pilot flow reduces debris-related clogging of solenoid ports.
• Slow-closing action lowers the risk of water hammer and system damage.
• Nonrising flow control handle allows precise flow adjustments without moving external components.

What installation and connection options are available?

The PGA series is available in globe and angle configurations for flexible placement, fitting common 1" FPT connections. Its PVC construction and captured solenoid make it straightforward to install and service in valve boxes for both inline runs and angle-mounted setups.

• One-inch female pipe thread (1" FPT) sizing for standard irrigation lines.
• Globe or angle body options to suit layout constraints.
• One-piece solenoid with captured plunger and spring for easy field servicing.
• Manual internal bleed lets you operate and adjust without allowing water into the valve box.

How should I set flow rates and prevent common issues?

Follow Rain Bird recommendations to keep supply-line velocity below 7.5 ft/s to minimize water hammer effects. For very low flows, use upstream filtration to protect the diaphragm and consider turning the flow-control stem partially closed to stabilize operation.

• Keep supply velocity under 7.5 ft./sec (2.3 m/s) to reduce water hammer.
• For flows under 5 GPM, install upstream filtration to prevent debris accumulation beneath the diaphragm.
• For flows under 10 GPM, turn the flow-control stem two full turns from fully open to improve control.
• Use the purple flow control handle when managing nonpotable systems for quick identification.

What maintenance and service features help reduce downtime?

The PGA valve was designed for rapid field service: the solenoid is a one-piece unit with captive parts and pilot filtering resists clogging. A manual internal bleed and slow-close operation also make testing and adjustments easier without repeatedly cycling the main controller.

• Captured plunger and spring prevent loss of parts during service calls.
• Double-filtered pilot flow reduces need for frequent cleaning of solenoid ports.
• Manual internal bleed allows pressure adjustments without controller activation.
• Durable PVC body resists corrosion and outdoor conditions for long life.

Who is this for? The Rain Bird PGA 1 in. valve is ideal for irrigation contractors, landscape professionals, and homeowners managing residential or light-commercial sprinkler systems who need a dependable, service-friendly control valve. It suits installations where pressure regulation, low maintenance, and clear identification of nonpotable lines (with purple flow-control handles) are important. Choose the PGA when you want a compact valve that balances adjustability, debris resistance, and straightforward field servicing.
