Compressed Air Best Practices - April 2008 - (Page 25) Compressed Air Industry PLASTICS BLOW-MOLDING | 04/08 | The discharge check valve, which should be installed down stream of a pulsation tank or receiver tank, will stop any high-pressure air from bleeding back into the booster when the machine unloads. This is an extra precaution in case of a leaking discharge valve on the booster. With the inlet check valve upstream of a receiver and the discharge check valve downstream of a receiver, correctly selected valves should not cause any abnormal maintenance problems. The receivers will dampen most of the pulsations going to and coming from the Booster compressor. Check Valve Example — (Be sure to check with vendor) Inlet (low-pressure) check valves: p p p p Valves may be designed for 2 psig on 2000 scfm of air at 134.5 psig of pulsating flow Discharge (high-pressure) check valve Valves may be designed for 2.1 psig on 2000 scfm of air at 614.7 psig of pulsating flow Materials — as recommended by vendors FLOWS FROM 165 TO 3,000 SCFM • PRESSURE TO 725 PSIG • WORLDWIDE DISTRIBUTION High pressure HPET Series compressed air dryers and HF Series filters improve productivity and protect blowmolding and thermoforming operations from damaging oil, water and particulate during the injection process. Since 1948, engineers from around the world have specified energy-efficient Hankison products to reduce operating costs and keep their air systems clean and dry.
