Unique “reverse flow” design permits equal pressure distribution on both sides of the diaphragm, regardless of line pressure, providing zero stress to prevent “stretching,” a common cause of valve failure.

21000 Series

  • 5 year trade warranty and 100% water tested
  • 200 PSI (13,8 BAR) rating
  • Unique “reverse flow” design permits equal pressure distribution on both sides of the diaphragm, regardless of line pressure, providing zero stress to prevent “stretching,” a common cause of valve failure
  • Reverse flow design for water conservation in the event of failure
  • Diaphragm’s self cleaning ports constantly flex, inhibiting sand and silt from blocking valve action
  • Brass shock cone for smooth operation and reduction of water hammer
  • Easy-to-use internal manual bleed lever; bleeds valve downstream; has positive stops for open and closed positions
  • Marine-grade S20P solenoid with stainless steel actuator
  • High-strength glass-filled body and cover with ¼” stainless steel cover bolts and mating brass body inserts
  • Brass non-rising flow control stem throttles valve from full open to closed position
  • Excellent for low volume irrigation
  • Contamination-resistant (CR)
  • Chlorine- and chloramine-resistant EPDM diaphragm material
