Bermad Hydraulic Pressure Reducing Valves

The Bermad IR-120-XZ is a hydraulically operated, diaphragm-actuated pressure reducing valve designed to deliver stable and accurate downstream pressure, even under varying upstream conditions. As water enters irrigation or municipal systems from mains supplies, pressure spikes and fluctuations can damage downstream components. This valve ensures reliable protection by automatically reducing high inlet pressure to a consistent, preset outlet pressure — regardless of upstream changes — and fully opening when line pressure drops.

Engineered for high flow efficiency, the IR-120-XZ features Bermad’s patented hYflow ‘Y’ body design, delivering ultra-low pressure loss and smooth hydraulic performance. Its Super Travel (FST) diaphragm and guided plug offer highly responsive, stable control, while the valve’s bolt-free, corrosion-resistant construction ensures simple maintenance and long service life.
