6. Commissioning

One-way flow control valves are used to regulate exhaust air flow rates with double-
acting cylinders. In the reverse direction, air flows through the non-return valve with
full cross-sectional flow.
Uncontrolled supply air and controlled exhaust hold the piston between air cushions
(improves motion, even with load changes).
Prerequisite
Cylinder is tubed up
Compressed air supply switched on.
Execution
1. Screw in the restrictors of the one-way flow control valves at first completely and
then loosen again one turn.
2. Start a test run.
3. Slowly open the one-way flow control valves until the desired piston speed is
reached.

A visual check must be carried out before each commissioning!
Prior to starting up the station, you will need to check:
The electrical connections
The correct installation and condition of the compressed air connections
The mechanical components for visual defects
(tears, loose connections etc.)
Eliminate any damage detected prior to starting up the station!
