This “value” is factorypreset and is set to allow normal air consumption when usingair tools.Should the air consumption exceeds the set value, e.g. the airline is severed, then the internal piston instantly shuts off themain flow. An integral bleed hole allows some air to flow though.This enables the line pressure to automatically resetthe AirGuard once the main line break is repaired.Management Responsibility:It is the duty of management to ensure a safe workingenvironment for their employees and that the equipmentcomplies with the Machinery Directive EN983 or “PUWER”(the Provision and Use of Work Equipment Regulations)EU Standard EN983-1996 (5.3.4.3.2) currently states:“Failure of flexible hose assemblies and plastic piping:If the failure of a flexible hose assembly constitutes awhiplash hazard or a fluid ejection hazard, it shall be restrainedor shielded”.Complies with the 2009 ISO4414 (5.4.5.11.1)“When failure of a hose assembly of plastic piping constitutesa whiplash hazard, it shall be restrained or shielded by suitablemeans and/or an air fuse for compressed air shall be mounted”.Function:Special Applications(P) is the inlet. Air passes the piston (1)and continues through the seat (3).The air flow, passing the piston, is sloweddown by means of length wise grooveson the outer side of the piston. If the flowis too high, the air cannot pass the pistonquickly enough, and the piston is forcedagainst the spring (2) and towards theseat. The maximum flow is shown in thegraph. If the value indicated is exceedede.g. if the hose suddenly breaks - theair supply is automatically shut off. Anintegral bleed hole allows some air to flowthough. This enables the line pressure toautomatically reset the AirGuard once themain line break is repaired.123SW *PStainless Steel AirGuard available in 1/2” sizeSome branches of industry with a high hazard potential, suchas chemical and pharmaceutical as well as clean room andoffshore technologies place extremely high demands on boththe safety of their employees and the protection of their facilities.Compressed air is typically used as an energy transfer mediumin 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 extremehazards as well as potential damage to expensive facilities andcostly production downtime.ABAASWSWSW1/4” - 3/8” - 1/2” 1/4” - 3/8” - 1/2” 3/4” - 1” - 2”Technical Data and Ordering InformationThread dimensions (mm) Weight Maximum Temperature Material P1 inlet P2 outlet Order Codeconnection (g) inlet range thread threadBSP A B SW pressure1/4” 48 - 22 30 female female P4GAA121/4” 58 49 22 36 Housing: male female P4GBA123/8” 59 - 27 58 aluminium female female P4GAA133/8” 71 59 27 62 Piston: male female P4GBA131/2” 65 - 30 78 18 bar-20 O C to 80 O C polyoxymethylenefemale female P4GAA141/2” 80 65 30 85 (255 PSIG)(-4 O F to 176 O F)male female P4GBA141/2” 62 - 28 132Housing:stainless steelPiston:polyoxymethylenefemale female P4GCA143/4” 76 - 30 / 36* 107 Housing: female female P4GAA16-20 O C to 120 O C1” 100 - 41 / 50* 300aluminium35 barfemale female P4GAA18(-4 O F to 248 O F) Piston:2” 130 - 70 / 80* 775 (500 PSIG)aluminium female female P4GAA1CNote: NPT version available on request - 1/4” high flow version available on request.311Parker Hannifin CorporationPneumatic Division - Europe
