AME 438 SU Modulating Control Actuator
Brand: Danfoss
AME 438 SU actuator is used with two and three-way valves type VRB, VRG, VF and VL up to DN 50 diameter.
Features- It automatically adapts its stroke to the valve end positions which reduces commissioning time (self stroking)
- Advanced design incorporates load related 'switch-off' to ensure that actuators and valves are not exposed to overload
- Safety function (spring up): In case of power failure or power switch off spring up function retracks actuator stem to end position; Further manual stem positioning is not disabled
