The new line of Model RCV groove/groove swing check valves come in sizes: 2, 2-1/2, 3, 4 and 6 inches. They are UL Listed and have FM Approvals for 300 psi water working pressure. The valves are available for “shotgun” usage (riser check valve arrangement) and for use as “non-return” valves in horizontal or vertical positions. They provide a leak-tight seal against pressures greater than 1 psi.
