Detailed Information

Description

LK 525 MultiZone 3R is a 3-way valve that can be used as a mixing valve or as a diverting valve in heating systems.

The valve is constructed so that the leakage is less than 0.1% of Kvs at 100 kPa. It also has a split linear characteristic which means that the regulation is good even at low flows and capacities.

The valve must not be installed with the motor underneath the valve unit. Please note that the motor can be installed in only one position.

The motor operates anti clockwise when the black conductor is powered and clockwise when the brown conductor is powered.

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°.
