Lever gearboxes GF 50.3 – GF 250.3 Worm gearboxes with base and lever Torques up to 45,000 Nm Information

Lever gearboxes If valves in technical process plants can only be operated via lever arrangements due to lack of space or design features, then these can be automated by using AUMA lever gearboxes. In combination with an AUMA multi-turn actuator, they form an electric lever actuator that can be operated from the control room. The gearboxes are suitable for open-close and modulating duty. Accessories Primary reduction gearing For reduction of the input torque, gearboxes in sizes GF 100.3 to GF 250.3 can be supplied with primary reduction gearing at the gearbox input. Position indicator AUMA lever...

[2] Flange for mounting of multi-turn actuator The flange sizes are according to EN ISO 5210 (optional DIN 3210). Primary reduction gearings can be fitted at the gearbox input side to increase the reduction ratio. Detailed information on AUMA multi-turn actuators can be found in the brochure ‘Product description Electric multi-turn actuators’.
