Internal pilot air supply
Festo P.BE−MPAL−EN en 1008NH
To avoid back pressures:
Optimise the ventilation and exhaust performance of
·
the valve terminal e. g. by using lar ger pipe diameters or
additional compressed air supply via pneumatic supply
plates with exhaust via silencers and exhaust plate.
Separate exhaust ducts by using pressure zones if
·
necessary (see Chapter 1.5.3).
Connections on the following components are available for
supplying the valve terminal:
To the pneumatic supply plate, type VMPAL−SP
To the right−hand end plate, type VMPAL−EPR−SP
If the operating pressure lies between 3 ... 8 bar
operate the pilot control of the solenoid coils with an inter
nally branched pilot air supply.
Note
Internal pilot air supply is branched centrally from sup
·
ply connection (1) for all solenoid coils. When operating
the valve terminal with several pressure zones the inter
nal pilot air supply is taken from the pressure zone,
which is directly adjacent to the right−hand end plate
(see Fig. 3/1 and Fig. 3/2).
