The Weathermatic Black Max MAX-DW-10 is a durable 1" solenoid-operated irrigation valve engineered for reliable performance in demanding conditions. Designed as a Dirty Water (DW) model, it resists contamination and keeps systems operating with minimal maintenance. Built from high-strength, glass-filled plastic with brass inserts and stainless steel hardware, the MAX-DW-10 delivers long service life and consistent flow control for residential and commercial landscape irrigation.

  • Durable construction: Glass-filled plastic body and cover, stainless steel cover bolts and brass body inserts for corrosion resistance and long life.
  • Contamination-resistant design: Reverse-flow diaphragm and self-cleaning ports reduce clogging from sand and silt; ideal for dirty water applications.
  • Reliable operation: S24B high-efficiency 24VAC solenoid provides positive opening at high pressures; valve is 100% water tested.
  • Performance specs: Flow range 0.2–130 GPM, rated to 225 PSI (15.5 BAR); electrical draw approximately 9.5 VA inrush / 5.7 VA holding (24VAC, 60Hz).
  • Serviceable features: Internal manual bleed lever, brass shock cone to reduce water hammer, and brass non-rising flow control stem for precise throttling.
  • Warranty & testing: Backed by Weathermatic’s trade warranty and manufacturer testing for reliable field performance.

Measuring approximately 5" long × 3.13" wide × 4.75" high, the MAX-DW-10 includes flow control and is available with NPT threads for standard underground installation.
