Series LG Laboratory Faucets with Water Quality Indicator Light (Duraline Control Valve)

Manufactured from premium materials including PVC, Natural Polypropylene, and High-Purity PVDF, our Series LG Lab Faucets are engineered for use with Distilled, Deionized, Reverse Osmosis, and Ultra-Filtered Water (Type I, II, III). These faucets are designed to meet the rigorous demands of laboratory environments, ensuring optimal water purity and safety.

Key Features:

  • Water Quality Indicator Light: Integrated with a state-of-the-art sensing system to monitor water purity levels ranging from 10k ohm/cm to 1 Meg ohm/cm. The intuitive display features a red or green light for easy interpretation—green signifies optimal purity above threshold levels, while red alerts to below-threshold purity.
  • Safe Operation: Powered through a wall transformer converting 120 VAC to 9VDC, enhancing operational safety and extending product lifespan.
  • High Flow Rate: Delivers a maximum flow of 2.5 GPM at 80 PSI when fully opened, tailored for efficient water delivery in demanding applications.
  • Versatile Design: Comes with a removable serrated barb tip, leaving a 1/4" Female NPT Outlet for easy attachment of various accessories.
  • Innovative "Duraline" Control Valve: Offers effortless operation from full flow to closed with a 120-degree turn, designed with a zero dead leg to prevent microbial growth.
  • Durable and Compliant: Manufactured without the use of elastomers, metals, or lubricants and exceeds FDA, USDA, and USP standards. The unique construction is ideal for high-traffic and intensive use settings.
  • User-Friendly: Features a black handle with white marker and "DI" text, adhering to SEFA code recommended practices for DI Water Applications. The positive stop at the off position enhances user experience by preventing over-tightening.

Specifications:

  • Max Operating Pressure: 150 PSI
  • Cord Length: 9 feet for flexible installation
  • Connection: 3/8" Female NPT inlet with a 3/8" O.D. tube x 3/8" MNPT compression tube fitting included for easy setup.

Sustainability and Maintenance:

  • Renewable Design: The Duraline control valve can be fully renewed by replacing the internal cartridge, ensuring a long service life and reducing environmental impact. Repair Kits can be purchased using the following link: REPAIR KITS
  • Ultra Smooth Internal Flow Path: Minimizes turbulence and potential for contamination, ensuring the highest quality water delivery.
