Irritrol R811-24VACG — Replacement Solenoid (2-Pack)

What is it and what's it for?

The solenoid is the valve's 'coil': the electrical part that receives the signal from the controller and does the mechanical work of opening or closing the water flow — like the little motor on an automatic garage door, but for water.

Real-world use cases

• At home: Your irrigation valve suddenly stopped opening, but the plastic body and water fittings are still fine — instead of replacing the whole valve, you swap just this part and save money.
• In a business or workshop: A parks maintenance crew can keep these replacement solenoids in stock to fix Irritrol valves on the spot, without stopping irrigation on a large field or garden while waiting for a whole new valve.

How to avoid buying the wrong one

• This is NOT a complete valve — it's only the electrical part. If your valve body is also damaged (leaks, cracks), this alone won't fix it.
• It's only compatible with Irritrol valves in the 2400, 2500, 2600, and 700 series — confirm your current valve's model before buying.
• It comes in a 2-pack, handy if you have more than one Irritrol valve failing or want a spare on hand.
