Detailed Information

Description

EMV 110 is a series of actuators for controlling LK 525 zone valves. The actuator features 2-point control (on/off) for flow distribution. On the top of the actuator there is an indicator showing which port on the valve is open. The actuator is easily mounted on the LK 525 zone valve using a clip; note that the actuator can only be mounted in one position on the valve.

In applications with a risk of condensation, icing, or high temperatures, an adapter (article number: 066177) must be installed between the zone valve and the actuator.

The zone valve must not be installed with the actuator positioned below the valve unit.
