The Irritrol 539001 Replacement Diaphragm is an OEM-quality service part engineered to restore reliable operation to Irritrol 2500 Series irrigation valves and several compatible models. This replacement diaphragm addresses common wear issues that cause valve leakage or failure to shut off, letting you service a single component instead of replacing the entire valve. It is a cost-effective repair option for both residential and light commercial irrigation systems.

  • Compatibility: Designed for Irritrol 2500 Series valves and compatible units including 2700APR, 2711APR, 2713APR, and 214B/214APR models; verify your valve model number before ordering.
  • OEM part 539001: Manufactured to match original Irritrol specifications for fit and reliable performance in the valve bonnet assembly.
  • Sealing design: The rugged double-beaded diaphragm provides a secure seal and helps maintain consistent operation even in systems with debris or hard water.
  • Easy installation: Service the valve by shutting off supply, opening the valve bonnet, replacing the diaphragm, and reassembling captive screws—no specialized tools required for most jobs.
  • Restores performance: Replacing a worn or torn diaphragm often stops continuous flow and restores proper valve closing and metering function.
  • Documentation: Parts breakdowns and an installation guide are available to assist with correct placement and torque procedures for your valve model.

Order the Irritrol 539001 diaphragm to quickly return your irrigation system to proper operation. If you are unsure about compatibility, check the model stamped on your valve body or consult the installation literature before purchasing.
