Clamp design minimizes process contamination

Products indicators L.J. Star sterile visual flow
L.J. Star has introduced a design concept to visual flow indicator assemblies. Designed for hygienic/sterile applications in pharmaceutical, food/beverage, brewery and biotech industries, the clamp type sterile visual flow indicator, or CT-SVFI, uses a patent-pending design to prevent the O-ring seal gaskets compression issues that lead to contamination associated with conventional screwed or threaded fittings.
The L.J. Star unit uses a mechanical stop design rather than screw threads said to apply precisely controlled compression to O-rings every time.
The product also provides up to 34 percent greater view area with the standard face-to-face dimensions. Units maintain an EN10204 3.1 certification, along with FDA and USP Class VI certified O-rings and is fully compliant with the requirements of the European Pressure Equipment Directive 97 / 23 / EC.
The product uses SF4 (15Ra EP) 316L stainless steel, with full material traceability. EPDM is the standard O-ring material, with silicone and other options available in tube OD sizes from ½ to 4 in. Glass material is made from borosilicate.
