The Danfoss actuator's modern design incorporates a "load switch" that prevents overloading of actuators and valves.

AMV 435 actuator is used with two and three-wayvalves type VRB, VRG, VF and VL up to DN 80 diameter and for AHQM DN 40-100. 

The actuator has several special functions:

• it automatically adapts its stroke to the valve end positions which reduces commissioning time (self stroking)
• valve flow adjustment feature; flow can be variably-adjusted from linear to logarithmic or opposite
• energy saving, cost reducing and energy efficiency improving anti-oscillation function
• the advanced design incorporates load related ‘switch-off’ to ensure that actuators and valves are not exposed to overload
