Irritrol (Richdel) 204MT 25mm Solenoid Valve with Manual Bleed Box of 20

This Box of 20 Irritrol (Richdel) 204MT Series 25mm Screw-Top Solenoid Valves is ideal for contractors, landscapers, maintenance teams, and large residential developments requiring a robust, debris-tolerant valve in high volumes. Unlike the jar-top 2400 Series, the 204MT uses a traditional screw-top bonnet design, offering greater pressure stability and exceptional durability in sites exposed to dirty or lightly contaminated water. For nearly 30 years, the 204 Series has earned a reputation as one of the most dependable, high-flow irrigation valves on the market.

Each 204MT valve incorporates an improved bonnet that interlocks with the diaphragm and body for superior pressure balance. The rugged, nylon-reinforced Buna-N diaphragm provides long service life and reliable sealing, while the high-flow, low-friction-loss design ensures optimal zone performance—ideal for larger areas or systems with long pipe runs. A manual external bleed allows quick flushing and activation during installation or servicing without running the controller.

Featuring heavy-duty PVC construction, an encapsulated solenoid, and a tamper-resistant design, the 204MT Series is easy to maintain and built for longevity. Each valve can be serviced without removing it from the pipework, reducing labour time on every project. For bulk installations where strength, water-handling tolerance, and proven reliability matter, this 20-valve contractor pack delivers outstanding value and consistency across all zones.
