Any additivesused in the air supply must be compatible withvalve materials.Operating temperature range:-40°F (-40°C) to 120°F (49°C)Mean life: Over 5 million cycles 75 PSI (5.1Bar) and 80°F (27°C).Diaphragm material: PolyurethaneHousing material: Zinc alloyEnd cap material: Noryl®GRAPHIC SYMBOLS:Figure 32.0 INSTALLATIONBefore performing any work, read this manualand study all figures. Assure yourself that youunderstand and can do what is required in eachstep. Failure to follow these instructions mayaffect quick release valve operation and mayresult in exposure to personal injury.Before installing the valve, set and block themachine or equipment in a secure position;close the air shutoff valve and exhaust airfrom air lines; and disconnect all electricalpower.2.1 Air Piping2.1.1 For fastest response time, use an inlet pipe sizeequal to or larger than the quick release valve size.Minimize the length of pipe between the quickrelease valve and air control valve. Keep the numberof fittings, bends and other restrictions in the inlet lineto a minimum.2.1.2 Piping should be free of foreign material such as pipethread sealant, metal chips, etc. Pipe and tubingends must be reamed after cutting to prevent areduction of effective pipe or tube diameter.Do not allow foreign matter to enter thequick release valve. Particles of foreignmatter can prevent diaphragm sealing andcause air leakage.2.1.3 Refer to 1.3 for air quality, additives and allowableoperating pressures.Table 2:PORT SIZESQRV Size Inlet Cylinder3/8 3/8 NPT or 1/2 OD Tube 3/8 NPT1/2 1/2 NPT or 5/8 OD Tube 1/2 NPT3/4 3/4 NPT or 3/4 OD Tube 3/4 NPT1 1" OD Tube 1" NPTTable 3:FLOW CAPACITY IN SCFM(m3/min) *QRV Size Inlet to Cylinder Cylinder toExhaust3/8 121 (3.4) 206 (5.8)1/2 172 (4.9) 256 (7.2)3/4 287 (8.1) 376 (17.2)1 Contact Factory* At 100 PSIG (6.9 Bar) inlet pressure with full pres-sure drop.
