are used to control air flow, e.g. for the piston speed of single-acting
and double-acting cylinders. The
throttle screw controls the air flow in the direction of the arrow. In the opposite direction, the
air flows via the non-return valve with full cross-sectional flow.
valves are mounted directly into the cylinder port, without accessories.
They can be turned through 360o
. To achieve inlet port flow control with single-acting cylinders,
the valve is fitted the other way round.
