AGF Manufacturing’s TESTANDRAIN Model 2511 is available with grooved connections on 1” and 1-1/4” models. Smaller grooved connec-tions provide faster field installation for a wider range of projects. A second access port allows for flexible drain line options during installation and the valve’s handle orientation permits vertical or horizontal installation. Options include code-required pressure relief valve and trim and a pressure gauge. The 1” valves are available with 2.8K, 4.2K, 5.6K, 8.0K, or 11.2K (ELO) orifice and 1-1/4” valves are available in all of those orifice sizes, plus 14.0K (ESFR) orifice. AGF Manufacturing.
