Features of the UNA series

nnnn

• Unaffected by back pressure and condensate

nnnn

temperature

nnnn

• No loss of live steam due to continuous

nnnn

water seal at the seat

nnnn

• No banking-up of condensate even with

nnnn

extreme load and pressure fluctuations

nnnn

• Particularly well suited for heat exchangers

nnnn

controlled from the steam side

nnnn

• Unaffected by dirt

nnnn

• Automatic thermostatic air-venting

nnnn

(Duplex design)

nnnn

Application

nnnn

Condensate discharge without banking-up,

nnnn

even at varying operating conditions and back

nnnn

pressure. Automatic air-venting (Duplex design).

nnnn

Also for the discharge of cold condensates and

nnnn

distillates, and for draining gas and compressed

nnnn

air systems (Simplex design).

nnnn

Pressure/Temperature Ratings and Designs **)

nnnn

Ideal for discharging cold condensates, distil-

nnnn

lates and condensates derived from chemical

nnnn

products (Simplex design)

nnnn

Repairable in-line

nnnn

Thanks to the rolling ball valve only reduced

nnnn

operating forces and small control units are

nnnn

required (compact, lightweight design for

nnnn

large flowrates)

nnnn

Internals made from corrosion-resistant

nnnn

stainless steels
