Valves
The MPA−S valve terminal can be fitted with 2x3/2−way valves,
5/2−way valves (single−solenoid and double−solenoid),
5/3−way mid−position valves and proportional directional
control valves.
All 5/2−way valves and 5/3−way mid−position valves can be
used under all operating conditions:
standard mode
reversible mode
low−pressure mode
vacuum mode.
Identifying the valves The valves on the MPA−S valve terminal are marked by
identification codes. By means of this identification on the
front of the valve, you can ascertain the equipment fitted on
your MPA−S valve terminal.
Ident. code Valve
B 5/3−way valve, open in mid−position
D Two single−solenoid 2/2−way valves, normally closed
E 5/3−way valve, mid−position exhausted
G 5/3−way valve, mid−position closed
H Two single−solenoid 3/2−way valves, control side 12 in basic position open, control
side 14 normally closed
I Two 2/2−way valves, normally closed
with dual−pressure operation: operating pressure at connection 1 or connection 5
with vacuum operation: operating pressure at connection 1, vacuum at connection 5
(e.g. for vacuum switching with reject pulse)
