Spool valve “V” ventilation port
Ventilation and bleeding of the spool valve. The port must not be obstructed.
Pilot valve “Y” exhaust port
Bleeding of the spool valve actuator chamber. An air pulse escapes here after
each stroke. The port must not be obstructed.
This port can be used to connect a stroke counter.
Bleed port high pressure side “Z1” and “Z3”
Discharge of the leakage from the high pressure unit and ventilation of the piston
back chamber. A bleed pipe can be connected. It is possible to safely discharge
the operational leakage on the high pressure side via this line.
Bleed port air side “Z
2
“, “Z
4
“ and “Z
6
“
Discharge of the leakage from the drive unit. A bleed pipe can be connected. It is
possible to safely discharge the operational leakage on the drive side via this line.
“SFP” purge port
Port for purging the piston back chamber. The piston back chamber on the high
pressure side can be purged with the appropriate gas via this port. The purging
process must be carried out at very low pressure. The bleed lines must discharge
the purge gas at zero pressure.
Alternatively, in single-stage double-acting gas boosters, the piston back cham-
ber on the high pressure side can be filled with a suitable gas, for example to pre-
vent the leakage from reacting with the ambient air.
Ports for the control system of the second pneumatic/air drive unit “F

Connections that allow to switch off the second drive unit. Only in combination
with the “Flexdrive” option.
