The range of movement of boiler valves is mechanically limited to 90°. There-
fore, it is easy to find the limits by turning the valve to the extreme limits using
the manual control knob or axle. Sometimes it may be difficult to determine the
opening direction of a 3-way valve installed in the network, e.g., if the manual
control knob is missing or the scale plate of the valve is installed incorrectly. To
make it easier to determine the direction, a few hints are given below for the
most common mixing valves on the market.
ESBE (3MG): The slide of the valve can be turned 360°. Turn the valve all the
way to the left (9 o’clock). The tapered side of the valve axle always faces to-
ward the slide. (the branch on the tapered side is closed).
TERMOMIX:
The slide of the valve is always on the side opposite to the taper
at the end of the axle.
If you can’t get the valve turned so that the slide moves between the hot wa-
ter branch and circulating water branch, the position of the valve cover must be
changed. We recommend having a plumber change the direction because of
the risk of water damage and burns.
