CAPACITY DIAGRAM

LK 527 MultiZone is a motorized 3-way ball valve for applications

in, for example heating, cooling and domestic water systems.

The zone valve is controlled by 3-point signal.

Assembly/disassembly of actuator on the ball valve is simple

and secure, using the clip-system. The zone valve must not be

installed with the actuator underneath the valve unit.

In case of a power failure, the valve stays in its current position.

When the power is switched off, the valve can be manually set by

the handle on the actuator.

Please note that the actuator can be installed in only one position.
