You can convert the valve terminal MPA−L at a later date and
adapt it to requirements by adding valve positions. The fol
lowing conversion work can be undertaken on the valve ter
minal MPA−L:
Conversion between ducted and unducted exhaust air
Conversion between internal or external pilot air supply
Conversion to different pressure zones
Adding valve positions (sub−bases)
Adding supply plates for additional pneumatic power
supply
The shortening of the valve terminal MPA−L by a few valve
positions is only possible if the tie rod system is created from
individual expansion pieces (see Tab. 5/1).
Information on permitted possibilities of combining MPA−L
components and accessories can be found in the Festo Cata
logue (see www.festo.com\catalogue).
The mechanical connection between the modules of the valve
terminal MPA−L is achieved via a tie rod system in the sub−
bases between the two end plates.
This tie rod system is used for valve terminal MPA−Ls that
consist of at least four VMPA1 sub−bases and supply via right−
hand end plates with lateral ports or two VMPA1 sub−bases
and a supply plate.
