Irritrol (Richdel) 205MT 25mm Solenoid Valve with Flow Control Box of 20

This Box of 20 Irritrol (Richdel) 205MT Series 25mm Screw-Top Solenoid Valves with Flow Control is designed for contractors, irrigation installers, councils, and developers who require durable, high-performance valves in larger quantities. Built for light-commercial and residential systems, the 205MT provides all the strength and reliability of the proven 204MT valve, with the added benefit of integrated flow control for precise zone management.

The rugged screw-top bonnet interlocks with the diaphragm and valve body to improve pressure stability and sealing performance, even under fluctuating conditions. Each valve includes a nylon-reinforced Buna-N diaphragm, corrosion- and UV-resistant PVC body, and a debris-tolerant internal design that performs well in bore, tank or slightly contaminated water supplies. A manual external bleed allows fast on-site flushing and manual testing without activating the irrigation controller, making installation and servicing fast and efficient.

The integrated flow-control stem allows installers to fine-tune individual zone output, correct overspray or misting, or completely shut off flow to a single valve during maintenance—an advantage not available on the standard 204MT. Each valve services easily without removing it from the system, reducing labour time across large installations. For contractors seeking robust, long-lasting 25mm valves with maximum control and outstanding value in a bulk pack, the 205MT Series is an excellent choice.
