LHS Hydraulic Heavy-Duty Actuator Series FCD LFENIM0003-00-AQ 7/14
2.5 Hydraulic Supply Pressure
To prolong actuator life use below recommended oil or equivalent. Periodically check that the oil is in good condi-
tion and clean. The cleanliness level for actuator without control system is minimum NAS 1638 Class 8 – ISO 4406
19/17/14. For actuators with control system the oil cleanliness level required by each control system component is
normally more stringent. Please verify with Flowserve Service or control system component Manufacturer.
Standard operating temperature range -29°C to 100°C (-20°F to 212°F).
Advised Maintenance Materials
For low temperature -60°C (-76°F) and High temperature 160°C (320°F) applications, consult Flowserve Limitorque
Fluid Power Systems.
2.6 Initial Operation
Before initial operation of the actuator, perform the following checks:
•
Check that all electrical supply, control and signal lines are properly connected, by following the dedicated
customer procedures;
•
Check that the pressure and quality of the supply fluids are as prescribed;
•
Check the absence of leaks in the hydraulic connections. If necessary tighten the pipe fittings.
