Pressure relief valve
The base of the control unit is equipped with a pressure relief
valve. Which prevents an inadmissible pressure build-up in the
inner control unit.
If required, the pressure relief vents into the clearance between
the base and the adapter of the control unit.
The pressure relief valve must not be mechanically blocked
under any circumstances.
