VGU Valve
Brand: Danfoss
VGU are pressure relieved 2-way normally closed (NC) valves, designed to be combined with:
- AVT Temperature actuators
- AMV(E) 20 / AMV(E) 30 electrical actuators
- AMV(E) 23 / AMV(E) 33 electrical actuators with spring return function
In combination with AVT temperature actuators and AMV(E) electrical actuators, valves can be used primarily in cooling systems.
