Installation
Mount valve on standard hydraulic manifold,tighten mounting bolts to specified torque.Connect hydraulic oil pipeline and electrical control wiring.Complete oil flushing,parameter calibration and performance test before commissioning.Keep clean during handling,prevent oil contamination.
Interface
‑Multi-pin aviation electrical connector
‑Hydraulic P,T,A,B pilot oil ports
‑Valve identification label
Feature
MOOG 79F series heavy-duty high flow three-stage servo valve.Typical faults:pilot stage blockage,feedback sensor failure,spool sticking,internal leakage.Inspect oil cleanliness and feedback signal before replacement.
Diagnostic
Fault phenomenon:output flow abnormal,zero drift,slow response,no action.Check oil contamination,electrical wiring,feedback sensor and spool condition.
Product Brief
79F180C3 is MOOG 79F series three-stage electro-hydraulic feedback hydraulic servo valve with large flow and robust structure,suitable for heavy-duty hydraulic test and large forming equipment,used for industrial hydraulic system maintenance and replacement.Strict oil cleanliness control is required in service.
