Product catalog summary
Pressure/Temperature Ratings and Designs
  • Specifications: The document provides pressure and temperature ratings for various types of Ball-Float Traps (UNA series) with different materials and standards (EN, ASTM). Each type has specific pressure (PMA) and temperature (TMA) limits at different conditions.
  • Materials: The materials used include EN-JS 1049, EN-JL 1040, 1.0460, 1.0619, 1.5419, 1.7335, and stainless steels, with ASTM equivalents provided for guidance.
  • Design Features: The UNA series is designed to be unaffected by back pressure and condensate temperature, ensuring no loss of live steam and no banking-up of condensate. They are suitable for heat exchangers and are repairable in-line.
  • Applications: These traps are used for condensate discharge without banking-up, automatic air-venting, and are suitable for cold condensates, distillates, and draining gas and compressed air systems.
  • Available Designs: The document lists various designs with different end connection options and orifice sizes for maximum differential pressure. Conversion between horizontal and vertical designs is possible for some types.
  • Capacity Charts: Charts are provided to show maximum hot condensate capacities for different orifice sizes and types, indicating the range of float-controlled orifices available.

UNA-1

• Unaffected by back pressure and condensate • No loss of live steam due to continuous water seal at the seat • No banking-up of condensate even with extreme load and pressure fluctuations • Particularly well suited for heat exchangers controlled from the steam side • Automatic thermostatic air-venting (Duplex design) Condensate discharge without banking-up, even at varying operating conditions and back pressure. Automatic air-venting (Duplex design). Also for the discharge of cold condensates and distillates, and for draining gas and compressed air systems (Simplex design). Pressure/Temperature Ratings and Designs **) Ideal for discharging cold condensates, distil- lates and condensates derived from chemical products (Simplex design) Repairable in-line Thanks to the rolling ball valve only reduced operating forces and small control units are required (compact, lightweight design for large flowrates) Internals made from corrosion-resistant stainless steels ') ASTM nearest equivalent grade is stated for guidance only. Physical and chemical properties comply with EN grade. ") For more information see data sheet.
