Pressure control valves belong to the group of pressure valves and their task is to keep the outlet pressure constant, despite a higher and changing inlet pressure (DIN ISO 1219-1). They are used in hydraulic systems where a second oil circuit with a lower pressure level (secondary circuit) is to be branched from a circuit with a higher pressure level (primary circuit), without the higher pressure in the primary circuit being affected. Pressure fluctuation in the main circuit caused by a system‘s various functions are kept away from the pre-control circuit, by reducing the pressure to a consistent level in the range of about 20...30 bar. The switching operation of all hydraulic devices being actuated in such a manner can be influenced by e.g. directional spool valves type HSR(F) acc. to D 7493 ++ or PSL(V) acc. to D 7700 ++. Types ADM 1.. and ADME 1.. were especially designed to cope with larger flows. The pressure reducing valves are available as cartridge valves, designs for direct pipe connection or for manifold mounting.

Start temperature down to -40°C are allowable (Pay attention to the viscosity range during start!), as long as the operation temperature during consequent running is at least 20K (Kelvin) higher. Biodegradable pressure fluids: Pay attention to manufacturer‘s information. With regard to the compatibility with sealing materials do not exceed +70°C.
