Replacement diaphragm assembly engineered for Superior 3/4" 950-series irrigation valves. This OEM-style assembly (part 16211) uses EPDM rubber components selected for resistance to reclaimed water and extended service life compared with commonly used Buna-N parts. The diaphragm is manufactured to the original dimensions for a consistent fit and simple replacement so you can return valves to reliable operation quickly.

  • EPDM construction: Resists ozone, chlorine, and reclaimed-water exposure to extend service intervals.
  • OEM-fit design: Dimensions and mounting points match original Superior 950-series diaphragms for backward compatibility.
  • Easy installation: Straightforward in-line replacement—no specialty tools required for most models.
  • Reliable operation: Maintains consistent valve performance and helps prevent leaks or irregular actuator response.
  • Maintenance-friendly: Keeps repair time and downtime low with a durable, long-lasting elastomer component.

This diaphragm assembly is intended as a direct replacement part for compatible 3/4" 950 valves. Before ordering, confirm your valve model and size to ensure fit. If you have questions about compatibility or installation, provide your valve model number and serial information to our support resources so we can confirm fitment and provide step-by-step guidance. Replace worn diaphragms proactively to maintain irrigation efficiency and reduce emergency repairs.
