ABB ST/K1.1

Electromotor Valve Drive

Product code: 2CDG120004R0011

The electromotor valve drive ST/K 1.1 is a proportional

valve drive for controlling heating valves via the ABB i-busÌøåÀå_.

The valve drive is mounted on thermostat valve bases.

The control is carried out via a continuous ABB i-busÌøåÀåâ

room temperature control. The continuous control value

enables a valve position with an optimum control-action

result. The actual valve position is indicated by 5 LEDs.

The valve drive has two external inputs for a presence

and window contact. Using the valve adapter supplied,

the valve drive can be used on many conventional

thermostat valve bases.
