Product catalog summary
Application and Features
The document describes a liquid level gauge with reflex glass suitable for neutral fluids and aggressive media, depending on the material resistance. It is designed for use with water and can handle a nominal pressure of 63 bar and a maximum temperature of 250°C. The gauge is constructed from acid-resistant steel or carbon steel, with options for non-standard lengths and specific designs for boilers and steam applications.
Materials and Construction
The body material options include acid-resistant steel X6CrNiTi18-10 and carbon steel P355NH. The gauge features flanged ends and a straight form, with sealing surfaces according to PN EN 1092-1 standards. The construction includes a safety ball check valve to cut off flow in case of glass breakage.
Dimensions
The document provides detailed dimensions for various parts of the gauge, including center-to-center distances and visible glass lengths. The weight of the components is also specified.
Pressure-Temperature Ratings
The gauge is rated for a nominal pressure of 63 bar, with pressure-temperature ratings dependent on the type of ball valves used. The document includes a graph illustrating the allowed working conditions.
Types and Ordering Information
Several types of gauges are available, differentiated by maximum temperature and the inclusion of safety ball check valves. The document provides an example of how to order a specific type using product numbers and specifications.
