The Weathermatic SB-15F-HP Silver Bullet 1.5-inch irrigation valve is a heavy-duty, in-line solenoid valve engineered for residential and commercial sprinkler systems. It operates on 24 VAC and includes an integrated flow control for precise zone balancing and reliable operation in buried installations.

  • Reliable reverse-flow design: Equal pressure distribution across the diaphragm reduces stress and prevents stretching, improving long-term performance and reducing failure risk.
  • Durable construction: High-strength glass-filled nylon body and cover with 1/4" stainless steel cover bolts and mating brass body inserts for corrosion resistance.
  • Performance specs: 150 PSI (10.3 BAR) maximum working pressure; flow range approximately 0.2–180 GPM, suitable for micro-irrigation to higher-flow zones.
  • Electrical & solenoid: Designed for 24 VAC controllers; marine-grade S20P solenoid. Typical inrush: ~9.48–10.66 VA; holding: ~5.11–5.97 VA depending on frequency.
  • Serviceability: Internal manual bleed lever bleeds downstream, non-rising flow control stem allows easy throttling, and self-cleaning diaphragm ports resist sand and silt.
  • Installation & testing: In-line FPT connections, 100% water tested and suitable for underground burial. Refer to technical documents for dimensions and pressure-loss charts.

Ideal for landscape professionals and homeowners seeking a robust, low-maintenance valve, the SB-15F-HP delivers reliable operation across varied irrigation zones and comes with a 5-year trade warranty. See supplied sales sheets and technical specifications for installation guidance and dimensional drawings.
