AUMA spur gearboxes are used for the operation of valves  (e.g. gate valves, globe valves).

• Type of duty:
  Short-time duty S2 - 15 min (Open-close duty)
  Intermittent duty S4 - 25 % (Modulating duty)
• They can either be operated in:
  - manual operation directly via handwheel
  - motor operation (electric multi-turn actuator
• Gearbox is prepared for mounting an actuator flange
• Clockwise rotation at the input shaft results in clockwise rotation at the output drive
• To reverse the direction of rotation of GST 10.1 - GST 30.1, a reversing gearbox GW 14.1 can be used 
• GST 10.1 – GST 16.1 are single stage gearboxes with intermediate wheel
  GST 25.1 - GST 40.1 are double stage gearboxes

Design features:

• Torques up to 16,000 Nm
• Reduction ratios from 1:1 to 1:22
• Output drive types according to ISO or DIN standard

Ambient conditions:

• High enclosure protection
• High quality corrosion protection
• Wide ambient temperature ranges
