Visual Level Indicators (VLI) High Pressure Line

Product catalog summary
Overview: This document provides comprehensive specifications and guidelines for Visual Level Indicators (VLI) used in high-pressure lines, detailing series types, materials, operating conditions, and pressure-temperature ratings.
Specifications: VLIs comply with PED 2014/68/EU and harmonized standards, available in series 36800-A, 36800-B, 36800-K, and 36800-O. Constructed from 316 & 316L stainless steel, they operate at pressures from 80 to 200 bar at 20°C, with temperatures ranging from -80°C to 400°C.
Design and Materials: The float chamber is made of 316 & 316L stainless steel, with a titanium alloy float. Screws and nuts are A2-70 (AISI 304) for high-temperature resistance, and gaskets are graphite with a stainless steel reinforcing net.
Process Connections: Includes female threads per ISO and ANSI standards, and butt weld ends per ISO/EN and ANSI standards. Special flange connections are also available.
Operating Conditions: Suitable for fluids with density ≥ 0.49g/cm³ and viscosity ≤ 600cSt. Maximum connecting distance is 5800mm for a one-piece design.
Pressure-Temperature Rating: A chart is provided for different flange types, indicating maximum pressure at various temperatures.
Float Selection: A diagram assists in selecting the appropriate float type based on operating conditions, with special considerations for steam or condensate applications.
Accessories and Certificates: Accessories include fixation brackets, magnetic switches, and transmitters. Test reports and certificates comply with EN10204:2004-3.1 standards.
Additional Notes: Emphasizes adherence to pressure-temperature ratings, noting that the lowest rating of any component sets the limitation. Special executions and additional notes are provided for specific applications.
Procedures: Installation instructions highlight the use of fixation brackets and magnetic switches, stressing the importance of pressure-temperature ratings.
Standards and Certifications: Compliance with EN10204:2004-3.1 for main pressure-bearing parts according to PED, referencing flange standards EN1092-1 and ANSI/ASME B16.5.
Recommendations: For steam or condensate applications, damping springs are recommended. Advises checking maximum permissible float pressure for higher temperatures.
