Bermad Direct Acting Pressure Reducers

The Bermad IR-1”PRV is a 25mm adjustable direct acting pressure regulator valve, purpose-built for precise pressure control in drip irrigation systems and low-flow applications. Ideal for both domestic and commercial use, it ensures constant downstream pressure for efficient dripper performance—even under fluctuating upstream pressure or demand.

Activated by a pressure-responsive diaphragm, the valve continuously adjusts to maintain a stable outlet pressure, optimizing irrigation system performance and protecting sensitive components. The low-flow variant, IR-1”PRV-05, is specially suited for conditions with near-zero demand, offering superior regulation in smaller zones with short drip lines.

Constructed with reinforced polymer and stainless steel components, the IR-1”PRV offers excellent chemical resistance, high mechanical strength, and long service life in demanding outdoor environments.
