Twinsburg, OH – March 10, 2020 – LJ Star announces an innovative new design concept to visual flow indicator assemblies that eliminates threads and gasket compression problems that lead to contamination.

Designed for hygienic/sterile applications in pharmaceutical, food/beverage, brewery and biotech industries, the new Clamp Type Sterile Visual Flow Indicator, or CT-SVFI, uses a patent-pending design to prevent the o-ring and gasket compression issues that lead to contamination associated with conventional screwed or threaded designs.

The CT-SVFI uses a mechanical stop design rather than screw threads to apply precisely controlled compression to gaskets and o-rings every time. This metal to metal stop provides equal axial force on the o-ring, eliminating a twisting or torsional movement of the seal.  This prevents stretching and bunching of the o-ring resulting in gaps and intrusion that can trap bacteria and contaminants.  Just as beneficial, the design better maintains alignment of the o-ring, glass and metal ID, allowing better drainability than any other inline sight glass on the market.  The CT-SVFI design actually gets to the root of contamination build-up, reducing cleaning issues and frequency.

Moreover, the new design concept offers easier assembly and disassembly than threaded-designed visual flow indicators. The clamp connection eliminates additional tools or specialized equipment for device installation.

The CT-SVFI also offers the largest possible viewing area consistent with mechanical integrity of the component. When compared to typical visual flow indicators, the CT-SVFI allows for a viewing area increase of up to 34 percent with the standard face-to-face dimensions.

The CT-SVFI maintains an EN10204 3.1 certification for steelwork, 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. L.J. Star’s CT-SVFI uses SF4 (15Ra EP) 316L stainless steel, with full material traceability. EPDM is the traditional o-ring material, with silicone and other options available in tube OD sizes from ½” to 4”. Glass material is high-quality borosilicate glass.
