Bermad IR-420-55 Series Metal Hydraulically Operated Pressure Reducing Valve with S.390 Coil

The Bermad IR-420-55 is a robust hydraulically operated, diaphragm-actuated pressure reducing valve with solenoid on/off control. Designed to maintain a constant downstream pressure regardless of fluctuating demand or upstream variations, this valve also responds to electrical signals for opening or closing, offering precise control in automated irrigation or water distribution systems.

Engineered with Bermad’s advanced hydro-efficient globe valve design and a fully supported balanced diaphragm, the IR-420-55 delivers exceptional flow capacity, low pressure loss, and accurate regulation, even at low flows. Its modular build enables in-line servicing, and the S.390 coil provides electrical actuation in a range of voltages and control configurations including Normally Open, Normally Closed, or Last Position.

Ideal for reducing water losses, managing pressure zones, and protecting downstream systems, this valve is a reliable and efficient choice for modern irrigation and municipal applications.

APPLICATIONS

• Pressure reducing stations in irrigation or municipal systems
• Downhill line pressure management
• Leakage and cavitation damage prevention
• Zone isolation and pressure balancing
• Control of “on-duty” or source valves
• Automated systems requiring remote valve actuation
