Equilibar
This company’s dome-loaded vacuum regulators are now available in an anodized aluminum version (photo). Previously, the regulators were only available in stainless steel or polyvinyl chloride. The lightweight, corrosion-resistant aluminum models are suitable for many vacuum applications, such as extrusion and forming systems, casting, molding and dehydration. The regulators provide accurate and precise control of vacuum pressure with just one moving part — a large, sensitive diaphragm that directly seals against a field of parallel orifices, acting as both the vacuum-sensing element and the valve. This design eliminates the internal friction of traditional vacuum regulators, which use a spring-loaded diaphragm to modulate a sliding valve shaft. — Equilibar, LLC, Fletcher, N.C.
