Detailed Information

Description

LK 525 MultiZone is a motorized 2-way zone ­valve for application in heating systems in which the flow through one or more zones is to be controlled. The zone valve has On/Off control and is ­designed with a turning slide which allows it to withstand a ­larger pressure difference and reduces the risk of it stalling after a long intermission. On the upper surface of the actuator is an indicator that shows which port is open or closed.

The zone valve must not be installed with the motor underneath the valve unit.

In case of a power failure, the valve cone stays in its current position. When the power is switched off, the valve can be manually set. Remove the motor and turn the spindle to your selected position. When the power is restored, turn the valve back to its original position and reinstall the ­motor.

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

The valve requires no maintenance but the installation should be checked regularly.

Questions & Answers

Is it possible to replace a Honeywell mixing valve with an LK 525 MultiZone with actuator?

Yes it is easy to replace and no adjustment is needed.

My mixing valve rotates in different directions: is there something wrong?

No, this is quite normal. The mixing valve will rotate randomly between ports A and B. Rotation takes place at an angle of 60°.
