3-way valve
Quick switching
The fast change-over in diverting applications reduces unnecessary energy consumption. This valve is extremely fast: it
change from A to B circuit taking only 3 seconds.
The job of the diverting valve is to divert hot water between the space heating and DHW production. Optimal heat produc-
tion is achieved through well-functioning cooperation between the diverting valve and the heat pump.
Great longevity
In order to reduce friction the valve housing is made of brass and has a Teflon-blended composite regulating cone, sealing
against specially prepared O-rings.
The actuator's basic design is uncomplicated with its integrated transmission. A micro processor based circuit board is
located under the cover and it among other things has an integrated anti-jamming program, which makes sure that at least
every 7th day a complete change-over cycle is made to prevent the regulating cone from jamming.
Other life-shortening hazards by developing a secure lid solution, 0-percentage internal leakage and corrosion protection
have been eliminated.
Compact design
This valve is easy to use, easy to control and easy to understand.
The actuator can easily be removed by just ushing the release button. Pushing the release-button once more allows it to
be re-attached - let go of the button, and the actuator is mounted.
At occasions when the heat pump for some reason shuts off or is not fully operational, an even flow may still be maintained
in both circuits by quite simply removing the actuator. The diverting valve will then automatically position itself so that flow
is allowed in both circuits simultaneously.
