Identifying the propor
tional pressure regulator The proportional pressure regulators on the MPA−S valve

identification you can ascertain the type of proportional
pressure regulator.

Pressure sensor plate
The pressure sensor plate serves for monitoring the following
depending on the type:
the operating pressure in channel 1 (type VMPA−FB−PS−1)
an external processing pressure (type VMPA−FB−PS−P1)
the pressure in the exhaust channels 3 and 5
(type VMPA−FB−PS−3/5).
By means of three LEDs the pressure sensor indicates
whether the pressure applied is less than, is equal to or
exceeds the setpoint value. An additional LED shows common
faults.
