The PEEP valve consists of a valve plate on an axis. The magnetic core at
the end of the axis is wound up by a magnetic coil.
The electric resistance of the coil is approx. 120 Ω.

During the inspiration phase, the magnetic core is activated by the
controller board. The membrane at the magnetic core closes the
expiration fitting.
The PEEP valve is open in idle state.
The extent of the final expiration pressure is defined by the tension of the
spring before the valve plate. The tension in the spring is adjusted by the
PEEP knob.
