Irritrol (Richdel) 2400 Series Diaphragm

The Irritrol (Richdel) 2400 Series Replacement Diaphragm is the genuine Santoprene diaphragm designed to restore full sealing performance to Irritrol’s most popular 25mm irrigation valves. As the key moving component inside the valve, the diaphragm controls water flow by opening and closing against system pressure. Over time, exposure to debris, chemicals, pressure cycling and wear can cause the diaphragm to stiffen, crack or leak—leading to valves that won’t close, won’t open fully, or begin seeping water.

This genuine Irritrol replacement diaphragm is manufactured from high-grade double-beaded Santoprene, providing excellent flexibility, chemical resistance and long-term durability. It is specifically engineered to maintain a leak-proof seal and deliver consistent performance across the entire operating pressure range. Replacing the diaphragm is fast and simple thanks to the Irritrol 2400’s famous jar-top (screwless) design, allowing top access without removing the valve from the irrigation line.

Ideal for contractors and homeowners performing maintenance on aging systems, the Irritrol 2400 diaphragm returns your valve to “as-new” performance and extends the service life of the entire irrigation system. Whether you’re servicing a single zone or maintaining multiple valves across a property, this genuine diaphragm ensures reliability, efficiency and trouble-free operation.
