Hydraulic fluid power. Four-port directional control valves. Mounting surfaces Ingestion-build-82396 only outdoor exposure under conditions1 Scope This International Standard specifies the dimensions and other data relating to surfaces on which four port hydraulic directional control valves are mounted in order to ensure their interchangeability. It applies to mounting surfaces for four port hydraulic directional control valves which represent current practice. They are generally applicable to industrial equipment.
