Hydraulic fluid power. Electrically modulated hydraulic control valves - Test methods for four-port directional flow-control valves Ingestion-build-79769 a) in the procedure1 Scope This part of ISO 10770 describes methods for determining the performance characteristics of electrically modulated, hydraulic, four port directional flow control valves. This type of electrohydraulic valve controls the direction and flow in a hydraulic system.
