Sambo Torque Limiters

Sambo Torque Limiters are automatic devices that control actuator input torque. They are designed to prevent actuator and valve damage due to over-torque.

How Does a Torque Limiter Work?

A torque limiter works by being installed directly to the gear box. In the event of an over-torque, a torque limiter permanently separates the drive shaft and the driven shaft. Decoupled shafts can be re-engaged manually.
