Pressure Relief Valves

Pressure Relief Valves

El Rosario pressure relief valves are designed to work in most agricultural irrigation systems. Their function is to relieve excess hydraulic pressure in the system. That is, if the pressure exceeds the limit at which it is calibrated, it opens and releases the excess, protecting the irrigation system.
