SANITARY VACUUM BREAKERS VBS17 DESCRIPTION The ADCAPure VBS17 is a series of sanitary vacuum breakers designed to automatically relieve or “break” an unwanted vacuum condition. Applications include venting and vacuum limiting in pipelines, reactors, heat exchangers, autoclaves, amongst others. These valves should not be used as vacuum control valves. The device is kept close by means of a spring-loaded valve and the pressure which acts on the underside of the plug. When pressure drops below the adjusted set pressure, unbalancing of forces causes the valve to open, allowing atmospheric air to enter the system. With raise in differential pressure results an increase in valve stroke and air flow. The units are available with an optional lift indicator to signal in case of opening, for monitoring or contamination detection purposes. MAIN FEATURES Metallic wetted parts machined from 316L stainless steel bar stock. Regulating ranges from -0,05 to -0,95 bar. FDA / USP Class VI compliant seals. Compact design with easy access for cleaning and inspection. Reduced dead leg. CAPACITY CHART STANDARD SURFACE FINISH Internal wetted parts: ≤ 0,51 µm Ra – SF1. External: ≤ 0,76 µm Ra – SF3. Other surface conditions see TIS.GIA – General information ADCAPure. Ultrasonic cleaning. Lift indicator. Compatible with NovAseptic® connectors. Different soft sealings for vapours and gases. Degreasing. Other construction materials on request. Clean steam and other vapours and gases compatible with the construction. * Values shown refer to the differential pressure between atmospheric pressure and the actual pressure inside the system. VBS17. CE MARKING – GROUP 2 (PED – European Directive) ASME BPE, DIN and ISO clamp ferrules. Others on request. Assembling and packaging in a clean room certified according to ISO 14644-1. The product is end capped and sealed with recyclable thermo-shrinkable plastic film, to avoid contamination. Vertical installation. See IMI – Installation and maintenance instructions.
