Special Applications
Stainless Steel AirGuard available in 1/2” size
Some branches of industry with a high hazard potential,
such as chemical and pharmaceutical as well as clean room and offshore technologies place extremely high demands on both the safety of their employees and the protection of their facilities. Compressed air is typically used as an energy transfer medium in these industries and is no means without its dangers: compressed air hoses can rupture or burst, as can fixed pipes. This may expose personnel working in such areas to extreme hazards as well as potential damage to expensive facilities and costly production downtime.
(P) is the inlet. Air passes the piston (1)
and continues through the seat (3). The air
flow, passing the piston, is slowed down
by means of length wise grooves on the
outer side of the piston. If the flow is too
high, the air cannot pass the piston quickly
enough, and the piston is forced against
the spring (2) and towards the seat.
The maximum flow is shown in the graph.
If the value indicated is exceeded e.g. if
the hose suddenly breaks - the air supply is automatically shut off. An integral bleed hole allows some air to flow though. This enables the line pressure to automatically reset the AirGuard once the main line break is repaired.
