Valves are part of the material exchange process and work in metering or feeding applications, function as rotary airlocks, or provide a combination of airlock and metering functions. A rotary valve in the pharmaceutical, chemical and food industry is used to dose and feed solid bulk products within the processes.
Rotary airlock; The basic use of the rotary airlock feeder is as an airlock transition point, sealing pressurized systems against loss of air or gas while maintaining a flow of material between components with different pressure and suitable for air lock applications ranging from gravity discharge of filters, rotary valves, cyclone dust collectors, and rotary airlock storage devices to ...
Saturation systems typically feature a variety of airlocks, including a stores lock for the transfer of supplies and a medical lock for secure passage of medical necessities or emergency evacuations. Complex "split-level" systems, which house divers at different pressure levels for varied work depths, may necessitate additional airlocks.
Flexible enclosure systems or specific products, such as the DoverPac, G2Pac and Continuous Liner, can be incorporated into various procedures in the manufacturing process to provide containment of potent pharmaceutical agents, protecting workers from harmful exposure and ensuring purity of the pharmaceutical agents by preventing contamination.
This extensive barrier is known as a restricted access barrier system, or RABS. A barrier cabinet using RABS design and control, is below the isolator in its ability to assure sterility assurance and containment, but far better than the traditional laminar air flow hood or "open process" designs that are progressively being phased-out by the ...
2004 A joint venture is established with Tianli Cryogenic Company, a pharmaceutical freeze dryer manufacturer in Beijing, China. 2006 The BOC Group is acquired by Linde AG and together form The Linde Group. Linde sells the vacuum division of BOC Edwards. BOC Edwards Pharmaceutical Systems remains part of the Linde Group, as an independent division.
A rupture disc (burst) Pressure-effect acting at a rupture disc A rupture disc, also known as a pressure safety disc, burst disc, bursting disc, or burst diaphragm, is a non-reclosing pressure relief safety device that, in most uses, protects a pressure vessel, equipment or system from overpressurization or potentially damaging vacuum conditions.
Air lock problems often occur when one is trying to recommission a system after it has been deliberately (for servicing) or accidentally emptied. Take, for example, a central heating system using a circulating pump to pump water through radiators. When filling such a system, air is trapped in the radiators. This air has to be vented using screw ...
