ISEN Flange sight glasses

In today’s competitive industrial landscape, rigorous monitoring and control of production processes are paramount to ensuring product quality and operational safety. Understanding this critical need, Valvelink Company is proud to introduce the ISEN line of Flange sight glasses, a specialized solution for tanks and vessels that provides clear, accurate, and reliable visual monitoring for your entire system.

ISEN Flange Sight Glasses for Tanks and Vessels

A Flange sight glass is designed for direct installation onto the wall of a tank, vessel, or pipeline. It allows operators to easily observe the flow, liquid level, color, clarity, and other internal conditions without opening the system. This not only saves time and effort but also enhances safety, prevents product loss, and helps maintain sterile conditions in specialized industries.

1. ISEN-FS-N (Plain): The Standard for Effective Observation

The ISEN-FS-N model provides fundamental and effective visual monitoring.

• Construction: Comprised of a stainless steel frame and a tempered or borosilicate glass disc.
• Function: Allows operators to clearly and precisely observe the flow of media.
• Gasket Material: Utilizes PTFE that is in accordance with FDA 177.1600.
• Max Temperature: +200∘C.
• Max Pressure: 10 bar.

2. ISEN-FS-K (With Scraper): For Uninterrupted Clarity

This model is specially designed for processes where media can obstruct the view.

• Special Design: Equipped with a wiper made from PTFE or Silica gel to effectively clean the inside surface of the lens.
• Benefit: Prevents crystallization, dust, or product buildup on the glass surface, ensuring a consistently clear view.
• Max Temperature: +200∘C.
• Operating Pressure: 5 to 10 Bar, depending on the glass diameter.

3. ISEN-FS-L (With Light): Enhanced Visibility in All Conditions

The ISEN-FS-L integrates a light source for superior observation.

• Application: Widely used in the food, wine-producing, beverage, and pharmaceutical industries.
• Design: Features a stainless-steel mirror lamp with a DC 24V power supply. The design ensures zero dead angles, strong illumination from a white cold light source, and is waterproof.
• Advantage: This Flange sight glass model makes it easy to view equipment and system status. An explosion-proof design is available as an option.
• Materials: SS304, SS316L, or as per customer requirement.
• Seal Materials: Silicone, EPDM, Viton, NBR.
• Working Temperature: −20∘C to +200∘C.
• Working Pressure: Up to 10 bar.
• Size: DN50-DN300 (2″-12″) or customizable.
• Connection Standards: DIN, SMS, ISO, IDF, BS, RJT, ASME, welding, or flanged connection as required.

4. ISEN-FS-R (Rectangular) and ISEN-FS-O (Oval): Versatility for Specialized Placements

The ISEN-FS-R/O models offer flexibility for unique equipment designs.

• Model ISEN-FS-R/O: The base flange is typically welded into or onto the vessel wall.
• Application: Ideal for observing the color, clarity, and level of a liquid, or for viewing the interface between two different fluids.
• Option: Can be supplied with a reflex lens, which uses refractive prisms for improved visibility of the liquid level.
• Technical Specifications (Model ISEN-FS-R/O):
  • Working Pressure: 0.6MPa, 1.6MPa, or as required.
  • Working Temperature: ≤250∘C.
  • Material: Carbon steel, stainless steel, Titanium, or other materials.
