Irritrol Replacement Diaphragm for 2400-2600 Series Valves 3/4 to 1 Inch | 100236

Overview

The Irritrol replacement diaphragm for 2400 and 2600 series valves is a genuine, field-ready part designed to keep irrigation systems performing as intended. Compatible with 3/4 inch and 1 inch valve ports, this diaphragm helps regulate water flow by sealing the internal chambers as the valve cycles, reducing the chances of slow leaks or inconsistent shutoff. Crafted to withstand typical irrigation pressure cycling, it’s a practical option for routine maintenance or after-downtime repairs.

Compatibility and fit

This diaphragm is engineered to fit Irritrol and Richdel 2400/2600 series valves, making it a convenient choice for mixed installations. It’s sized to work across common residential and light commercial setups, helping keep zones flowing smoothly.

Key benefits

• Restores reliable sealing to prevent leaks and erratic valve cycling.
• Maintains consistent flow control under pressure fluctuations.
• Durable elastomer material resists wear from frequent start-stop cycles.
• Simple tool-free or basic-hand-tool installation reduces maintenance downtime.

Fit and installation tips

• Verify compatibility with Irritrol 2400 and 2600 series valves.
• Ensure port size matches 3/4 inch or 1 inch connections.
• Prepare basic tools; replace the diaphragm with the valve depressor tool if available.
• Inspect nearby seals and gaskets; replace if worn.
• Reassemble and test valve after replacement, checking for steady operation.

Real-world use

Ideal for seasonal maintenance, valve leaks, or upgrading aging components, this diaphragm supports even water distribution in lawns, gardens, and landscape beds without requiring specialized equipment.

Quality and material considerations

The diaphragm uses a resilient elastomer compound designed to endure recurring pressure cycles and mineral-rich water. It resists compression set and maintains a dependable seal, helping to extend the valve's service life between full replacements.

What to expect after installation

Most users notice quicker valve response and steadier shutoff once the diaphragm seats. Periodic inspection of seals keeps the assembly performing reliably across seasons.
