Reduction ratio
The reduction ratio within gearing and primary reduction gearing reduces the required
input torques and increases the operating time.
Factor
Mechanical conversion factor for actuator size determination:
Input torque = required valve torque (output torque)/factor
Type of lubricant
AUMA abbreviation for type of lubricant used in the gear housing.
Danger of explosion when using inappropriate lubricant in potentially explosive
atmospheres!
→
Do not use gearboxes with F21 lubricant in potentially explosive atmospheres.
→
Do not mix different lubricants.
Explosion-proof version
(option)
Gearboxes may only be used in potentially explosive atmospheres if explosion-proof
version is indicated on the name plate. In explosion-proof version, other (reduced)
valve torques and input speeds apply than in weatherproof version.
Version
The first letter of the version indicates the position of the worm shaft in relation to
the worm wheel (view on input shaft).
The second letter indicates the direction of rotation at the output drive (view on
housing cover) for clockwise rotation at the input shaft.
