Section 4: Lubrication
4.1 Lubrication Inspection
The actuator is lubricated for the duration of its service life; under normal working
conditions it is not necessary to replace or rell the oil. However, it is recommended to
check the oil level every 3-5 years using holes 1 or 2 (per Figures 27 and 28) depending on
what orientation the actuator was mounted.
The actuator is tted with oil plugs (parts 1, 2), such that any assembly on the valve has at
least one oil plug on the upper part of the housing and one on the lower part.
A spherical head lubricator (part 3) is tted on the coupling block for the proper greasing of
the inside thrust or sliding bearings.
The actuator is supplied with oil and greased where necessary.
Should maintenance become necessary, the following OILS are recommended:
Ambient temperature from -20 °C to +85 °C
• SHELL - OMALA S4 WE 320 or equivalent
Ambient temperature from -40 °C to +85 °C
• SHELL - TELLUS S4 ME 46 or equivalent
Ambient temperature from -55 °C to +65 °C
• SHELL - TELLUS S4 VX 32 or equivalent
