Ball-Float Traps UNA PN 16 - PN 160
FLOWSERVE
GESTRA
Features of the UNA sries
 Unaffected by back pressure and condensate temp镩rature
 No loss of live steam due to continuous water seal at the seat
Օ No banking-up of condensate even with extreme load and pressure fluctuations
 Particularly well suited for heat exchangers controlled from the steam side
Օ Unaffected by dirt
 Automatic thermostatic air-venting (Duplex design)
Օ 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)
Օ Internals made from corrosion-resistant stainless steels
UNA 14/16 v DN 15 - 25
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).
