Hunter PGA-101 1″ Solenoid Valve with Accu-Sync AS-ADJ Adjustable Pressure Regulator

Achieve professional, dynamic pressure regulation and ensure ultimate zone containment using this trade-grade hunter pga valve kit. Specifically combined to protect sensitive, low-flow drip line networks and micro-irrigation systems from catastrophic high-pressure blowouts, this comprehensive package pairs the heavy-duty Hunter PGA-101 1″ BSP solenoid valve with the precision Accu-Sync AS-ADJ adjustable regulating module. It provides an all-in-one mechanical solution for commercial estates, agricultural grids, and multi-zone residential landscape installations.

Industrial Strength Core with Active Downstream Regulation

High-volume primary water mains frequently run under intense static pressures that exceed the safe operating limits of thin-walled surface or subterranean drip pipes. The robust Hunter PGA valve is constructed from premium, fabric-reinforced PVC with an internal double-beaded diaphragm system to withstand extreme water hammer waves. When combined with the Accu-Sync unit, the system actively monitors and clamps the downstream line velocity, maintaining a safe, rock-solid output pressure regardless of fluctuating incoming mainline conditions.

Why This Hunter PGA & Accu-Sync Assembly is the Professional Benchmark:

• Fully Adjustable Calibration: The AS-ADJ dial permits smooth, custom on-site pressure settings ranging from 1.4 Bar to 7.0 Bar (20 to 100 PSI).
• Dedicated Micro-Irrigation Protection: Perfect for downsizing high-velocity mainlines down to the gentle, precise pressures required by micro-sprays and drip lines.
• Globe and Angle Configuration: Versatile PGA internal body styling permits straightforward installation in both standard straight linear runs or deep 90-degree valve box bends.
• Internal Manual Bleed: Features a fully integrated internal and external manual bleed screw for quick, tool-free system priming and winterization checks.
• Commercial Grade Durability: Heavy-duty structural shell remains completely unaffected by liquid chemical fertilizer flushes, organic acids, and continuous high-pressure strain.

• Pressure Regulation Range: 1.4 Bar to 7.0 Bar (20 to 100 PSI)
• Electrical Actuator: Heavy-Duty 24V AC Solenoid Coil with Captive Plunger
• Minimum System Requirements: Requires a minimum continuous flow rate of 1.2 m³/hr (20 L/min) for optimal pressure calibration

Assembly & Commissioning Advice from Our Engineering Team:

To compile the system cleanly, isolate the main water supply and thread your 1″ BSP pipe connections home using professional PTFE tape on the plastic threads. Unscrew the standard solenoid actuator from the PGA valve body, insert the Accu-Sync AS-ADJ regulator base block into the exposed port, and then thread the 24V AC solenoid coil directly into the top of the Accu-Sync module. Connect the multi-core valve wires to your digital 24V AC outdoor irrigation controller. Once the system is active, turn the cross-hatched Accu-Sync dial until your inline downstream pressure gauge matches your exact micro-irrigation operating threshold.
