Product catalog summary
Pressure/Temperature Ratings and Designs
This section provides detailed pressure and temperature ratings for various types of Ball-Float Traps (UNA series). Each type is associated with specific materials and their corresponding EN and ASTM standards. The document lists the maximum allowable pressure (PMA) and temperature (TMA) for each type, highlighting the differences in performance at varying temperatures.

Features of the UNA Series
The UNA series is designed to handle back pressure and condensate temperature without loss of live steam. It is suitable for heat exchangers controlled from the steam side and is unaffected by dirt. The series includes automatic thermostatic air-venting and is ideal for discharging cold condensates and distillates. The traps are repairable in-line and feature a compact, lightweight design.

Application
The traps are used for condensate discharge without banking-up, even under varying operating conditions and back pressure. They also support automatic air-venting and are suitable for draining gas and compressed air systems.

Available End Connections and Overall Length
This section details the available end connections for different UNA types, including flanged, screwed sockets, socket-weld, and butt-weld options. It provides the overall length measurements for each connection type and size.

Available Designs
The document outlines the available designs for each UNA type, specifying the end connection options and orifice sizes for maximum differential pressure. It also distinguishes between Simplex and Duplex designs, with additional features like flow control and automatic air-venting.

Capacity Charts
Capacity charts are provided to show the maximum hot condensate capacities for various orifices and sizes available in the UNA series. These charts help in selecting the appropriate trap based on the required capacity and operating conditions.
