The piston speed of pneumatic drives,
both advancing and retracting, can be
regulated using one-way flow control
valves. This is done through suitable
restriction of the flow rate of compressed air in exhaust air or supply air
direction.
With the one-way flow control valve
GRLA or GRLZ, the flow control function
works in one direction only (exhaust
air or supply air); the non-return function works in the opposite direction.
With the throttle valve GRLO, the flow
control function is active in both
directions.
The flow control function creates an
adjustable annular gap inside the
valve. This gap can be increased or decreased by turning the knurled screw
or slotted head screw. The required restriction can be set with the help of
this adjusting element.
The standard nominal flow rate qnN is
the volumetric flow rate
standard conditions at an operating
pressure of p1 = 6 bar and an output
pressure of p2 = 5 bar, measured at
room temperature t = 20°C.

The standard flow rate is measured at

Speed adjustment through flow control on
both sides is often used with single-acting or
small cylinders. The benefit of this app
