Irritrol Nyglass Solenoid Master valve - Watermark Approved

The Irritrol IV25FC is a high-performance, WaterMark-approved 25mm master valve designed specifically for Australian conditions. Constructed from extremely durable 30% glass-filled nylon (Nyglass), this valve delivers exceptional strength, corrosion resistance and long-term stability—making it ideal for both residential and light-commercial irrigation systems. Its large, balanced diaphragm and slow-closing mechanism minimise pressure spikes and water hammer, ensuring reliable system protection and smooth operation across all zones.

Engineered for outstanding hydraulic efficiency, the IV25FC features the lowest frictional losses in its class, allowing higher flow rates with reduced pressure drop. The 14-path perforated Nitrile diaphragm offers superior debris resistance, making it well-suited for installations where minor contaminants may be present. With a threaded bonnet for quick access, WaterMark certification, and Australian-made construction, this valve has earned a reputation for reliability and consistent field performance.

The integrated flow control handle allows precise zone adjustment, from fine throttling to complete shutoff—offering greater versatility during system balancing and maintenance. A manual internal bleed enables activation without flooding the valve box, and the “tamper-resistant” flow-control handle ensures settings remain secure. Built tough, easy to service, and optimised for clean, reliable master control, the Irritrol IV25FC sets the benchmark for Australian irrigation valve quality.
