Irritrol Nyglass Solenoid Mastervalve - Watermark Approved 20/Box

This Box of 20 Irritrol IV25FC Nyglass 25mm WaterMark Solenoid Master Valves is the ideal bulk solution for contractors, irrigation installers, developers, and councils requiring a high-performance, Australian-made master valve for large-scale projects. Built from extremely strong 30% glass-filled nylon (Nyglass) and certified to WaterMark standards, the IV25FC delivers exceptional durability and reliable performance in both residential and commercial installations.

The IV25FC is engineered with one of the industry’s lowest friction losses, delivering outstanding hydraulic efficiency and maintaining strong downstream pressure across all zones. Its 14-path perforated Nitrile diaphragm provides excellent debris resistance, while the large balanced diaphragm ensures smooth operation without the need for a spring. The slow-closing design minimises water hammer, protecting pipes, fittings, and downstream components from damaging pressure spikes.

This bulk pack includes 20 valves—each equipped with an ergonomic flow-control handle for precise adjustment, a threaded bonnet for fast servicing, and a manual internal bleed for activation without flooding the valve box. With high durability, Australian manufacturing quality, and proven long-term reliability, the IV25FC is an outstanding choice for master valve protection in large irrigation installations.
