One-way flow control valves are used for regulating the exhaust air volume of double-acting drive units. In
the opposite direction, the air flows through the flow control valve having a full cross-sectional flow.
The piston is clamped between air cushions by free supply air and throttled exhaust air (improvement of the
operating behaviour even if the load changes).
