Features of the UNA Series:
- Function independent of back pressure and condensate temperature
- Steam loss-free operation through water seal formation
- Unobstructed drainage even with pressure and flow fluctuations
- Particularly suitable for steam-side controlled heat exchangers
- Insensitive to dirt
- Automatic venting by thermostat (duplex version)
- Suitable for discharging cold condensates, distillates, and chemical product condensates (simplex version)
- Maintenance possible without removing the Body from the pipeline
- Due to rolling ball closure, only low operating forces are required, with correspondingly small dimensions of the control elements (small installation volume and low weight with high flow rates)
- Internal parts made of corrosion-resistant stainless steels
- UNA 14, 16, 45, 46, 38: Body convertible for adapting the flow direction horizontally left or horizontally right or vertically, can be converted later
- UNA 45, 46 DN 40-65 optionally available with MAX controller for extremely large quantities (Normal/MAX controller not convertible)
Application:
Unobstructed discharge of large condensate quantities even under changing operating conditions and with back pressure. Automatic venting / start-up venting (duplex version); for discharging cold condensates and distillates, and for draining gas and compressed air lines (simplex version).
