Bermad IR-3/4"PRV Adjustable Direct Acting Pressure Regulator Valve for Drip Irrigation

 DOWNLOAD PRODUCT BROCHURE

The Bermad IR-3/4"PRV is an adjustable, direct acting pressure regulator valve designed for accurate and reliable pressure control in drip irrigation systems. Ideal for both domestic and commercial applications, this valve is particularly effective in low-flow scenarios and systems with relatively short drip tube lengths.

Activated by a pressure-responsive diaphragm, the valve constantly balances the upstream hydraulic pressure with the preset spring force to deliver a consistent downstream pressure, regardless of supply fluctuations or demand changes. The IR-3/4”PRV-05 low-flow version offers exceptional stability even under near-zero flow conditions, making it a preferred solution for sensitive irrigation zones and seasonal variability.

Constructed from high-strength, corrosion-resistant composite materials, this pressure reducer is engineered for long-lasting performance and precision. Its user-friendly design allows for easy installation in any orientation, as well as simple in-line inspection and servicing.
