Bermad 200 IR-21T 2 Way 50mm Solenoid Valve for Mains/Bore Water with Flow Control

The Bermad IR-21T 50mm Solenoid Valve is a high-performance, hydraulically operated control valve designed for accurate on/off control in mains or bore water irrigation systems. Powered by line pressure and controlled via an internal feed-and-bleed hydraulic loop, this diaphragm-actuated valve delivers smooth, drip-tight operation in response to electric signals.

Integrated with Bermad’s TRIO manual selector, the IR-21T allows full flexibility — enabling manual open, auto, or manual close functions — making it ideal for systems requiring both automated and hands-on control. Its durable reinforced nylon body and high-efficiency flow path ensure low-pressure loss, high flow capacity, and long-term resistance to chemicals and cavitation.

With user-friendly maintenance and reliable performance under variable pressure conditions, the IR-21T is perfectly suited for computerized irrigation networks, drip systems, greenhouses, and mastervalve applications.
