Low-sulfur forged valve bodies
Low-sulfur content forged valve boded with extended weld tangents are now available for ITT Industries' Pure-Flow hygienic diaphragm product line. These controlled sulfur devices were developed to solve common orbital welding issues, such as sulfur content mismatch and universal orbital weld head concerns, in the bioprocessing and pharmaceutical industries. The line features forged 316L stainless steel material, with sulfur content compliant to ASME Bioprocessing Equipment (BPE) 2002 Standard, Table DT-3. Weld tangents are equivalent to the lengths specified for ASME BPE-compliant fittings. Together, these features are designed to eliminate welded tube extensions, and allows for use of commonly used orbital welding equipment without the need for narrow or offset weld heads.
Wall-mounted gowning racks
Designed for use in cleanroom environments and electronic assembly areas, these wall-mounted gowning racks are constructed of chrome-plated steel with an electropolished stainless steel finish. Hanger slots, hanger tubes, or hook styles are available. Plastic shelf markers are available for the hanger slot and tube models. Racks are offered in standard lengths of 48, 60 and 72 inches; custom sizes available upon request.
Hose tracking system
Hose track assembly tracking system uses a radio frequency identification tag encoded with a serial number and encapsulated into each hose assembly. The tag never contacts the interior of the hose and is enclosed with silicone on the outside. It is unaffected by cleaning processes. A portable, hand-held reader/writer identifies each assembly by its tag's serial number, and personnel can log and track ongoing wear-related events, along with cleaning dates and the number of batches of material that have been processed.
Membrane technology speeds flow rates
The Supor EKV 0.2-µm sterilizing grade filter is designed to accelerate drug manufacturing flow rates by as much as 50 percent.
