Air supply is immediately shut off when volume flow exceeds a specific value. The maximum admissible
flow is factory-set in such a way that a standard application of pneumatic equipment is ensured.
Pressure drop amounts to 0.05 to 0.3 bar. In the case of failure, the hose guard blows off through a
small nozzle. After repairing the hose break, the hose guard can be set to zero again.

Standard_EN_983_1996:
According to EN 983:1996 § 5.3.4.3.2 the hose guard protects individuals, systems and machines from
injuries or damages caused by lashing hose lines in the event of hose breaks.

Function:
The air passes the piston and continues through the seat. The air stream is slowed down by means of
lengthwise grooves on the piston surface. When the volume flow is too high, the air cannot pass the
piston quickly enough, thus the piston will be pressed against the spring. If the maximum admissible
flow is exceeded, e.g. when the hose suddenly breaks, the air supply will automatically be shut off.
