3/2-way air valve
The main air is always at the
3/2-
way air valve (5) max. 1 m
away from the PKL. The control
line from the actuating valve (4)
on the customer's site to the
PKL may be longer (e.g. 50 m).
For longer supply and control
lines, the charging time of the
PKL
is several seconds. For
long air lines, set
a pause and
duty time on the Electronic Tim-
er AP (1) to a minimum of at
least 5 seconds. If shorter lines
are used, reduce these times
accordingly, e.g. to 2-3 sec-
onds.

3/2-way air valve
Operate several PKL in parallel
with just one control and an actu-
ating valve (4), if required.
The connection lines from the
3/2-way valve (5) to the PKL must
be max. 1 m
long, otherwise the
control piston or the membrane in
the PKL moves too slowly and
does not reach the end position.
If required, install the actuating
valve (4) at a larger distance if
additional 3/2-
way air valves (5)
are used.
If several PKL are in operation,
the supply line must not be longer
than 50 m.
