Interstage Blowdown ValveSUCTION VALVEUNLOADER ASSEMBLIESDescriptionThe Quincy suction valve unloader assembly consistsof unloading assemblies on the suction valves, havinga plunger to contact the suction valve reed and anunloader pilot valve (113320 or 113321 series) toautomatically regulate the passing of air tank pressure to the unloading arrangement.Continuous Run OperationSuction valve unloader assemblies are recommendedfor use on Quincy compressors where the compressoris to run continuously and a constant pressure is to bemaintained. The purpose is to automatically unseatthe suction valve of the compressor when the airsupply is greater than the demand.Unloading occurs when air tank pressure is sufficient to overcome pilot valve spring pressure. Thecheck ball is then unseated, allowing air tank pressure to pass to the unloader assemblies. The compressor will run unloaded until the air tank pressuredrops to a predetermined level. At this time, theaction of the ball is reversed, shutting off air tankpressure to the unloader assemblies and venting theunloader to atmosphere. This allows the compressorto load. The drive, either electric motor or engine,runs continuously and must be started and stoppedmanually. 113321 series pilot valves feature a togglelever which can be flipped to provide manual unloading.Dual Control OperationDual control operation is designed to provide achoice between "start/stop" or "continuous run" operation. The 113320 series pilot valve can be set for"start/stop" operation by turning the knurled knob atthe end of the pilot valve (refer to illustration for113320 series pilot valve) clockwise until it stops.Under these circumstances, a pressure switch is required to stop the motor. Failure to use a pressureswitch, with the pilot valve locked out, will result inunsafe conditions.113320 & 113321 series pilot valves feature aninterstage blowdown valve which bleeds interstagepressure back to atmosphere when the compressor isrunning unloaded. This reduces the unloaded horsepower.InstallationThe pilot valve is mounted directly into the air tank.Compressors in the field, not equipped with thesecontrols, can be converted. Consult your local Quincydistributor for assistance with conversion procedures.ServiceIf a change in pilot valve operation is detected, remove the pilot valve from the air tank and check thescreen in the inlet of the pilot valve for obstructions.Clean the screen if necessary.AdjustmentThe unloading pressure is adjustable and is regulatedby turning the unload adjustment hex nut (refer topilot valve illustrations). Turn the hex nut clockwiseto increase and counterclockwise to decrease theunloading pressure.The differential (difference between unloadingand loading pressure) is set by turning the differential adjustment hex nut (refer to pilot valve illustrations). Increase the differential pressure by turningthe hex nut clockwise - decrease by turning counterclockwise. Make all adjustments in small increments.Tighten the locknuts after adjustment.DECALS3WARNING !1A pressure switch must be incorporated whenever 113320series pilot valve is employed as part of the control system.DecalsThe compressor will operate in the continuous runmode if the knurled knob is turned counterclockwiseuntil it stops.QT-15 Industrial / Air Master50250-102, February -BDescriptionserial number & nameplatedecal, CAUTION!, MANUALdecal, DANGER!,"Air from this."Quincy Compressor203501 Wismann Lane, Quincy IL - 62305-3116
