coatings electrostatically, while pro- viding the highest possible quality fin- ish. Less paint and water is used, re- sulting in lower disposal costs and reduced hazardous waste. The AquaBlock System can handle single or multiple applicators. Its compact de- sign allows it to be easily retrofitted into existing manual or automatic fin- ishing systems, or it may be easily reconfigured for a future system. With the AquaBlock System, color changes can be achieved in about 60 set, 15 set if utilizing the AquaBlock + System.

Diaphragm Valves P/ash-0-Matic Valves Inc. Cedar Grove, NJ.

Plast-0-Matic Valves Inc. an- nounces the addition of a Teflon Dia- phragm Model to their line of thermo- plastic relief valves. Designed to provide smooth, highly sensitive re- sponse, this new model has no wetted elastomers, making it superior for use with both ultrapure liquids as well as highly aggressive liquids. Because of its large diaphragm area, the valve pro- vides far greater sensitivity and is more

responsive than conventional relief valves resulting in higher flow poten- tial with lower pressure drop. The model also incorporates a patented safety design feature, which provides advance visual warning of a diaphragm failure. This permits the valve and sys- tem to continue operating until main- tenance service can be scheduled, thereby avoiding a costly system shut- down. The nonleaching feature of Te- flon also makes the Series RVDT valve ideal for use with ultrapure water and concentrated etchants. The valves are available in % in., 3/4 in., and 1 in. sizes with various body materials, including PVC, Polypropylene, PVDF (Kynar) and Teflon,
