Pressure control valve

The pressure control valve is integrated in the suction pipe between the
vacuum pump and ice condenser chamber. During certain, specified
process phases, it interrupts the volume flow to the vacuum pump (see
chapter 2.2.1 - "General information on freeze-drying").

CAUTION

Observe the installation direction of the pressure control valve (see
illustration below)!
