Atos modular relief valves are available as direct acting (HMP) or double stage (HM and KM) valves. Relief valves are designed to limit the upper pressure value. Atos offers two sizes of these: NG06 and NG10.
Maximum pressure: 350 bar, maximum flow: from 35 l/min (HMP) to 120 l/min (KM)
Relief valves discharge oil supplied by the pump to the tank and stabilize the pressure in the line in which they are installed. Unlike safety valves, the HMP, HM and KM valves can operate continuously. The valve opening pressure is adjusted by turning the knob (or screw) – turning it to the right increases the pressure. Atos offers double and single valves as well as operating in various channels: P, A, B or A and B.
