ChemTite® Ethylene™ FLO-VU® Sight Flow Indicator, PTFE and Glass Wetted Surfaces
The ChemTite® Ethylene™ FLO-VU® Sight Flow Indicator has a Lexan® outer safety shield with an unobstructed 360° view to protect the glass from external damage and to provide scatter protection (two options: 360L PFA/PTFE Lined and 360M Unlined). The FLO-VU 360L sight glass: 1" through 12" diameter, featuring a full 360° unobstructed view with the high temperature and near-universal corrosion resistance of PTFE.The unique PTFE/Viton®* seal design is an envelope-type gasket which provides a secure, bubble-tight seal even in applications with extreme thermal cycling.
Product Features & Benefits
- ENERGIZED SEAL DESIGN: PTFE/Viton® Energizer gasket provides a secure, bubble-tight seat even in applications with extreme thermal cycling. Silicone energizer option for fluid services over 350°F.
- LEXAN® POLYCARBONATE IMPACT SHIELD: A Lexan® outer safety shield with an unobstructed 360° view to protect the glass from external damage and to provide scatter protection (360L PFA/PTFE Lined and 360M Unlined). Polycarbonate or Slotted Metal Shields available.
- 100% TESTING AND CERTIFICATION: Each unit is subject to a 1.5X MAWP hydrostatic pressure test and a 100 psig helium mass spectrometry test before shipment. (Helium test on ½” – 6” only. Passes steam-cold water cycling tests (ASTM F-423).
- PFA/PTFE and GLASS WETTED SURFACES: PFA/PTFE and borosilicate glass wetted surfaces offer high temperature with maximum corrosion resistance and absolute product purity.
- RUGGED CONSTRUCTION: All FLO-VU® sight indicators have heavy-duty tie rods and flanges to limit deformation under heavy external loads and reduce glass stress.
- AVAILABLE OPTIONS: Unlined 316 Stainless Steel Flanges with the FLO-VU® 360M, PFA/PTFE lined with the FLO-VU® 360L.
