The FEBCO 850 Series 1-1/2 in. Double Check Valve Assembly provides reliable backflow protection for non-health-hazard cross-connections. Built with a bronze body and quarter-turn ball shutoffs, this compact, top-entry assembly meets common plumbing codes for irrigation, fire line, and industrial non-potable applications.

  • Bronze body construction for corrosion resistance and long service life.
  • Nominal 1-1/2 in size with NPT (ANSI/ASME B1.20.1) female threaded end connections.
  • Quarter-turn ball valves (shutoffs) for quick isolation and service.
  • Rated to 175 psi working pressure; operating temperature range 32°F–140°F.
  • Top-entry, modular design with replaceable seats and captured springs for fast in-line maintenance.
  • Ideal for small-diameter applications (1/2 in to 2 in) requiring non-health hazard protection.

Designed and manufactured to industry standards, the FEBCO 850 Series simplifies installation and maintenance while protecting potable systems from contamination. Consult local codes and a licensed plumber or backflow specialist for proper selection and installation.
