Take complete control over your commercial landscape irrigation zones with the professional-grade Hunter Accu Sync Pressure Valve Regulator AS-ADJ Drip module. Engineered by the world-class water management specialists at Hunter Industries, this highly advanced, fully adjustable downstream pressure regulation unit turns any standard solenoid valve into a dedicated, precision-controlled delivery hub for micro-irrigation and sensitive drip line setups across the UK.

When you are managing commercial glasshouses, extensive domestic estate lawns, or complex municipal flower beds, excessive municipal mains water pressure can completely destroy your irrigation infrastructure. High line pressure causes micro-sprayers to mist wildly, splits delicate drip tubing, blows emitters out of their seats, and forces zone control valves to weep. By installing the premium Hunter Accu Sync system directly onto your existing control valves, you introduce a mechanical safeguard that maintains a perfectly consistent downstream flow, protecting your expensive irrigation equipment from sudden pressure spikes.

Dynamic Downstream Pressure Tuning from 1.4 to 7.0 Bar

What truly separates the AS-ADJ model from fixed-pressure alternatives is its fully customisable, adjustable dial mechanism. This specific module allows system designers and landscaping contractors to dynamically fine-tune the zone pressure anywhere between 1.4 bar (20 PSI) and 7.0 bar (100 PSI). This massive operating window makes it an incredibly versatile asset for projects that feature a mix of high-demand spray zones and highly sensitive, low-pressure micro-irrigation lines.

Furthermore, because the Hunter Accu Sync is designed for direct retrofitting, it screws effortlessly into the solenoid cavity of all Hunter ICV, PGV, and IBV series commercial valves. This completely eliminates the need to cut into your main PVC or MDPE pipes to install bulky, independent inline plastic pressure regulators. It simplifies your manifold layout inside underground valve boxes, reduces the number of potential leak points, and saves your crew substantial labour time on-site during technical multi-zone builds.

Key Features and Engineering Benefits

• Fully Adjustable Dial: Allows users to manually dial in exact downstream pressure parameters ranging from 1.4 to 7.0 bar.
• Direct Solenoid Integration: Mounts directly onto standard Hunter ICV, PGV, and IBV commercial series valves for a tidy, inline footprint.
• Maintains Uniform Flow: Ensures that all drip lines and micro-emitters operate at their peak engineered parameters without misting or line failure.
• Glass-Reinforced Construction: Manufactured from premium, industrial-grade glass-filled nylon to withstand harsh hydraulic shock and high-pressure surges.
• Enhanced System Reliability: Extends the operational lifespan of downstream drip lines, fittings, and emitters by mitigating aggressive water hammer risks.

Professional Installation and Tuning Guide

Integrating your new Hunter Accu Sync adjustable module into an existing zone valve is a straightforward process. First, isolate the main water supply and bleed off any residual line pressure from the zone. Carefully unscrew the existing solenoid coil from the top of your Hunter PGV or ICV valve body. Screw the Accu-Sync adapter module directly into that vacant solenoid cavity, ensuring the internal O-ring sits perfectly flush to prevent weeping.

Next, thread your original solenoid coil directly into the top female port of the newly installed Accu-Sync module. Reconnect your wiring to your irrigation controller as normal. Turn the main water supply back on and activate the zone. Using the integrated adjustment knob on the side of the module, slowly dial the selector until the built-in scale matches the exact working pressure required by your downstream emitters. For ultimate accuracy, we always recommend verifying your settings with an inline pressure gauge down the line.
