A18 Series - TFT's PRV (pressure relief valve) operates in an adjustment range from 90 to 300 psi (6 to 21 bar) with easy to see increments of 90, 125, 150, 200, 250, and 300 psi (6, 9, 10, 14, 17 and 21 bar). Each pressure relief valve includes an OFF position. The pressure relief valve meets NFPA 1901 PRV requirements. The aluminum casting is hardcoat anodized, and TFT-powder coat finished inside and out for maximum corrosion protection. For direct use on pump flanges, the TFT pressure relief valve works with Darley, Waterous, or Hale bolt hole patterns. Relief valves are available with 2" (51 mm) male pipe thread, 2.5" male NH (64 mm) thread, or 2.5" (64 mm) Victaulic® connection on the discharge spout. Available adapters include 2.5" (64 mm) and 3" (76 mm) NPT male and female threaded inlets for mounting the TFT pressure relief valve to plumbing. All A18 Series PRV's come standard with an intergated galvanic isolator for maximum corrosion resistance.
