Bermad IR-420 Series Metal Hydraulically Operated Pressure Reducing Valve
| DOWNLOAD PRODUCT BROCHURE |
The Bermad IR-420 is a hydraulically operated, diaphragm-actuated pressure reducing valve designed to accurately regulate downstream pressure in irrigation and water distribution systems. By responding to fluctuating upstream pressure and varying flow demands, it ensures a stable, constant downstream pressure, protecting pipes, fittings, and emitters from pressure damage.
The valve is compatible with two-way or three-way pilot controls, allowing versatile setup across a wide range of irrigation applications—from mainline regulation at pump stations to field zone pressure control for drippers, sprinklers, or pivots. Its robust construction, hydro-efficient design, and user-friendly maintenance features make it an ideal choice for demanding agricultural environments.
