13.4 Comments on the 3-way solar ball valve
IMPORTANT: A patented pressure compensation system was built into the
solar ball valve to prevent a pressure increase during switching. If a switching
action is interrupted (e.g., power failure), the desired position can be set with the
manual emergency control.

ball seating joint with
pressure compensation
system
The ball seating joint with the patented pressure compensation system
must always be installed on the side with higher pressure (pump side)
because otherwise it is non-functional and the ball valve may be
destroyed. The ball seating joint with the pressure compensation holes
can be converted using the spanner provided. In as-delivered condition, it
is in the middle position.
