HIGH RESOLUTION AND ACCURACY FOR PIPING SIZES 1\/4″ TO 1″<\/h2>\n

Equilibar precision vacuum regulators (EVR) are designed specifically to control a\u00a0highly stable inlet pressure across widely varying input conditions. These regulators show very little effect due to variation in supply vacuum or changes in flow rate. Equilibar precision vacuum regulators work differently than traditional vacuum control valve designs. The EVR uses a flexible diaphragm as the only moving part. This diaphragm is used to directly seal against the internal valve orifices, eliminating the \u201cstiction\u201d commonly found in traditional vacuum control valves that rely on dynamic O-ring or wiper type seals. The Equilibar design is frictionless and can control vacuum with very high resolution.<\/p>\n
