Bermad D100 IR-21T 2 Way 25mm Solenoid Valve for Mains/Bore Water with Flow Control

The Bermad IR-21T is a 25mm solenoid-actuated control valve engineered for reliable on/off performance in irrigation systems using mains or bore water. Designed with a hydraulically operated diaphragm and an internal feed-and-bleed loop, this valve ensures smooth and precise control under varying supply pressures.

Equipped with Bermad’s TRIO manual selector, the IR-21T provides complete operational flexibility—allowing manual opening, automatic control, or manual closing—ideal for installations where remote control is complemented by the need for on-site override.

Made from reinforced nylon and stainless-steel components, the IR-21T offers excellent chemical resistance and durability in harsh irrigation environments. Its flow-efficient globe pattern, high flow capacity, and simple in-line maintenance make it a dependable choice for drip systems, greenhouses, landscaping, and energy-saving irrigation networks.
