The Superior 950 Series Diaphragm Assembly is a direct replacement for internal diaphragms used in Superior 950 irrigation and electric valves. Molded in EPDM rubber, this assembly resists reclaimed and recycled water exposure better than Buna‑N, restoring reliable sealing and consistent valve performance across repeated cycles.

  • EPDM construction: Durable rubber compound formulated to resist chlorine and reclaimed water, extending service life compared with Buna‑N alternatives.
  • Backward-compatible fit: Designed to match OEM dimensions for Superior 950 series valves (part numbers 16211–16216) so replacements install without modification.
  • Available sizes: Offered for 1 in, 1-1/2 in, and 2 in valves (SKUs 16212, 16214, 16215); select the matching variant for your valve size.
  • Performance range: Compatible with typical 950 Series operating ranges — flow rates roughly 5–320 GPM and system pressure up to 200 PSI (model dependent).
  • Easy installation & maintenance: Replace the diaphragm using the official 950 disassembly instructions; inspect the seat disc, spring, and bonnet for wear and clean debris before reassembly.

This diaphragm assembly provides a cost-effective way to maintain or repair Superior 950 Series valves and helps prevent premature failure in recycled-water or high-chlorine environments. Order the correct SKU for your valve size and refer to the official 950 service manual for step‑by‑step removal and reassembly guidance. If you are unsure about fit, confirm your valve model markings or consult a qualified irrigation technician before installation.

Maintenance tip: when replacing the diaphragm, inspect related internals (rubber seat disc, diaphragm spring, bonnet) and remove trapped debris from the solenoid cavity. After reassembly, cycle the valve and check for a watertight seal and correct operation.
