Pressure zone separation with sub-bases
Sub-base for the
proportional pressure
regulator
The sub-base (type VMPA-...) for the proportional pressure
regulator always has a pressure zone separation and this is
not therefore marked additionally on the exterior of the
sub-base. Pressure zone separation takes place:
– for the channel (1) on the left side of the sub-base.
– for the channels (3) and (5) on the left and right side
of the sub-base.
If the propor tional-pressure regulator is to regulate the
operating pressure for the valves on the MPA-S valve
terminal, the valves must be positioned to the right of the
proportional-pressure regulator.
Sub-bases to the valves On the sub- ba se s wi t h in te gra te d pressure zone se para t i o n the
sepa ra ti o n is made in th e cent re of the sub- ba se , i.e . on the
– MPA1: after the second valve position
– MPA2: after the first valve position.
The sub-bases are available in the following designs:
– only supply channel (1) separate
– supply channel (1) and exhaust channels (3) and (5)
separate
