AUMA GK bevel gearbox for valves, up to 16,000 Nm, 90° axis

AUMA GK is a bevel gearbox installed between the electric actuator and the valve. It increases the torque and turns the axis by 90°. It is used on large gate valves where the output torque of the SA actuator is not sufficient. Supplied with an actuator or as a replacement.

In the SA + GK combination the torque range is 120–16,000 Nm. The range also includes the coaxial spur gearbox GST with the same range in combination with SA and the multi-turn GHT (SA + GHT, 32,000–120,000 Nm). Reduction ratio and valve attachment are selected per data sheet.

Key features:

• Bevel gearing, 90° axis
• 120–16,000 Nm in combination with SA
• Supplied with actuator or as replacement
• Range also includes GST and GHT (with SA up to 120,000 Nm)

Specifications:

• Type: bevel gearbox
• Function: torque increase, 90° axis change
• Torque in SA + GK combination: 120–16,000 Nm
• Output speed: reduced by gear ratio
• Reduction ratio, attachment: per data sheet
• Design: mechanical, non-electrical unit

Application: Large gate valves where the output torque of the SA actuator is not sufficient.

Scope of supply: Gearbox of the selected size; reduction ratio and attachment per data sheet.

Before ordering: Before ordering, specify the valve type and attachment, required torque, actuator type and required reduction ratio.
