Steam Traps, Steam Monitoring
Gestra UNA 14
Flowserve Gestra Rolling ball float steam trap with automatic thermostatic air vent.
Rating : PN 25
Material : Nodular iron body, Stainless steel internals. Hastelloy thermostatic membrane.
Max. Differential press. : 13 Bar
Conn. : Screwed /Flanged end
Size : DN 15/DN 20/DN 25
U/ Heat exchanger, nut/kernel silo, bulkings, etc. Ball float steam traps
Regulating characteristic:
Opening and closing response independent of condensate temperature.
Suitable for applications with high fluctuations of the steam pressure and condensate flowrate.
Simplex control: without thermal venting
Duplex control: with thermal venting (venting unit with membrane, bellows or bimetallic device).
Features:
- Robust and wear-resistant regulator with long service life, direct response characteristic, some with non-return valve action
- also for applications with high backpressure
- trap bodies for horizontal, vertical or angular lines.
Main applications:
Draining of:
- heat exchangers and heating coils controlled on the steam side.
- steam distribution mains
- steam lines: saturated steam (Duplex) and superheated steam (Simplex)
- turbines
- compressed air systems, cold condensates, distillates from gas lines (Simplex)
