F15B2211/3057 - CPC Classification

Classification description:

Circuits for servomotor systems; Directional control characterised by the type of valves; Assemblies of multiple valves having multiple valves for a single output member, e.g. for creating higher valve function by use of multiple valves like two 2/2-valves replacing a 5/3-valve having two valves, one for each port of a double-acting output member
