Bermad D150 IR-21T 2 Way 40mm Solenoid Valve for Mains/Bore Water with Flow Control

The Bermad IR-21T 40mm Solenoid Valve is a hydraulically operated, diaphragm-actuated control valve designed for high-efficiency irrigation systems operating on mains or bore water. Using an internal hydraulic feed-and-bleed loop, the valve responds instantly to electric signals, providing drip-tight opening and closing for precise zone control.

Equipped with Bermad’s TRIO integrated selector, the IR-21T allows manual override with three positions: open, auto, or closed — offering full operational flexibility for maintenance or system testing. Engineered for durability, it features a reinforced nylon body, chemical-resistant components, and a high-efficiency globe design that minimizes friction loss and maximizes flow.

The IR-21T is ideal for computerized irrigation systems, master valve control, drip zones, and applications where stable performance under fluctuating supply pressure is essential. Its compact design and user-friendly maintenance make it a preferred choice for professional landscape and agricultural installations.
