UNA Series

UNA14, UNA16, UNA27H, UNA38, UNA39, UNA45, UNA46, UNA special

Features of the UNA series:

  • Unaffected by back pressure and condensate temperature
  • 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
  • Unaffected by dirt
  • Automatic thermostatic air-venting (Duplex design)
  • Ideal for discharging cold condensates, distillates 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

Application

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).
