Interstate SUCTION VALVE UNLOADER ASSEMBLIES Description The Quincy suction valve unloader assembly consists of unloading assemblies on the suction valves, having a plunger to contact the suction valve reed and an unloader pilot valve (113320 or 113321 series) to automatically regulate the passing of air tank pressure to the unloading arrangement. Continuous Run Operation Suction valve unloader assemblies are recommended for use on Quincy compressors where the compressor is to run continuously and a constant pressure is to be maintained. The purpose is to automatically unseat the suction valve of the compressor when the air supply is greater than the demand. — Unloading occurs when air tank pressure is sufficient to overcome pilot valve spring pressure. The check ball is then unseated, allowing air tank pressure to pass to the unloader assemblies. The compressor will run unloaded until the air tank pressure drops to a predetermined level. At this time, the action of the ball is reversed, shutting off air tank pressure to the unloader assemblies and venting the unloader to atmosphere. This allows the compressor to load. The drive, either electric motor or engine, runs continuously and must be started and stopped manually, 113321 series pilot valves feature a toggle lever which can be flipped to provide manual unloading. Blowdown Valve 113320 & 113321 series pilot valves feature an interstage blowdown valve which bleeds interstage pressure back to atmosphere when the compressor is running unloaded. This reduces the unloaded horsepower. Installation The pilot valve is mounted directly into the air tank. Compressors in the field, not equipped with these controls, can be converted. Consult your local Quincy Compressor Distributor for assistance with conversion procedures. Service If a change in pilot valve operation is detected, remove the pilot valve from the air tank and check the screen in the inlet of the pilot valve for obstructions. Clean the screen if necessary. Adjustment The unloading pressure is adjustable and is regulated by turning the unload adjustment hex nut (refer to pilot valve illustrations). Turn the hex nut clockwise to increase and counterclockwise to decrease the unloading pressure. The differential (difference between unloading and loading pressure) is set by turning the differential adjustment hex nut (refer to pilot valve illustrations). Increase the differential pressure by turning the hex nut clockwise - decrease by turning counterclockwise. Make all adjustments in small increments. Tighten the locknuts after adjustment. Dual Control Operation Dual control operation is designed to provide a choice between “startistop” or “continuous run” operation. The 113320 series pilot valve can be set for “startistop” operation by turning the knurled knob at the end of the pilot valve (refer to illustration j%r 113320 series pilot valve) clockwise until it stops. Under these circumstances, a pressure switch is required to stop the motor. Failure to use a pressure switch, with the pilot valve locked out, will result in unsafe conditions. DECALS A pressure switch must be incorporated whenever 113320 series pilot valve is employed as part of the control system. Decals Item # The compressor will operate in the continuous run mode if the knurled knob is turned counterclockwise until it stops. 11 21 31 QT-15 50250-101 Qty.
