The HS and KS sequence valves enable the connection of an auxiliary hydraulic system when the pressure in the main system exceeds the setting pressure of these valves. The HS valve is a direct acting valve, while the KS valve is a double stage valve.

Atos pressure compensators are designed to maintain a constant oil flow rate regardless of pressure changes. HC, KC and JPC-2 valves are designed for plate mounting in systems with proportional and ON/OFF directional valves.

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.

The HR, KR and JPR check valves are available in four sizes: NG06, NG10, NG16 and NG25. They can be direct acting or pilot operated valves. Their purpose is to allow the oil to flow in only one direction.

HG, KG and JPG valves are pressure reducing valves, spool type. Atos has produced four sizes of such plate valves: NG06 (HG), NG10 (KG), NG16 (JPG-2) and NG25 (JPG-3).

The HQ, KQ and JPQ throttle valves of the Italian company Atos are manufactured in four sizes: NG06, NG10, NG16 and NG25 and in versions with meter in or meter out control.
