Lubrication Inspection
The actuator is lubricated for life, therefore under normal working conditions it is not
necessary to replace or refill the oil. However it is recommended to check the oil level every
3-5 years using holes 1 or 2 depending on mounting position.
The actuator is fitted with oil plugs (parts 1, 2), so 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. The actuator
is supplied with oil and greased where necessary.
