The Irritrol® 2500 Series is a classic example of making a great valve even better. Irritrol has taken its proven 205 Series of valves to the next level by adding a full menu of features including a patented “floating metering system” for consistent performance in dirty water applications and a rugged, double-beaded diaphragm for long-term performance with no leakage. The 2500’s manual internal bleed enables the valve to be opened without filling the valve box with water. And servicing is made easy and efficient with captured screws.
