Precise flow adjustment, control or blocking
One-way flow control valves and functional combinations
With or without throttle function – piloted non-return valves block air flow
consistently and completely in one direction. The blocked connection is opened
by means of a pneumatic control signal. The additional throttle function creates
a functional combination. This permits infinite adjustment of the piston speed.
One-way flow control valve GRLA
+ non-return valve HGL
= functional combination
Functional combinations …
… control the piston speed of a drive
by throttling the exhaust air. In one
direction, the exhaust air can be regulated, whilst in the opposite direction
it can flow through unhindered. As
long as the control signal is present,
compressed air will flow freely through
the valve from or to the cylinder. If the
control signal is cancelled, the valve
blocks the compressed air, thus allowing the cylinder to be briefly stopped.
whilst in the opposite direction flow is
blocked. This blocking can be cancelled via a pneumatic signal. These
valves are used as a stop function to
“block“ any sagging occurring due to
a load on a cylinder’s piston rod.
Non-return valves (piloted)
HGL/HGL-…-QS-…
The piloted non-return valve has a
blocking function. Flow passes
through the valve in one direction,

Functional combination with
GRXA-HG-…-QS-… (piloted one-way
flow control valve)
Speed regulation with additional
function for brief intermediate stop
included: Functional combination with
GRXA-HG-…-QS-…
When the pneumatic control signal
drops, the valve blocks the exhaust air
of the drive, thus preventing undesired movement of the piston rod.
