Multi-turn gearboxes for motor operation of gate valves and globe valves GHT 360.1 Torques up to 80,000 Nm Information

Multi-turn gearboxes Where a large fluid flow has to pass through a pipeline under high pressure, an actuator with high output torque is necessary to operate the required high pressure gate valve. An example would be in a large power plant where large quantities of vapour at a pressure of 250 bar or more are transported from the boiler to the turbines or within the feedwater supply of the steam generating boiler. With the SA 07.1 – SA 48.1 multi-turn actuators, AUMA covers a torque range of up to 32,000 Nm. Torques up to 80,000 Nm can be achieved by combining an AUMA multi-turn actuator...

RR [5] [6a] [4] [1] LL [6b] [2] [3] 2010-09-06 [1] Housing In the basic version, the housing is produced from high quality spheroidal cast iron to be able to withstand the high loads during the entire operation. [2] Valve attachment ■ ■ The valve attachment consists of: the mounting flange for mounting the gearbox to the valve and the output drive for transmitting torque to the valve stem. The following output drives are available: ■ B2 (standard) This output drive is integrated into the hollow shaft of the gearbox. The torque is transmitted via a parallel key. ■ A or AF Stem nut for...
