Description
UNA 3.. are steam traps with ball float and needle valve for
high-pressure applications. The steam traps can be used
for all operating conditions, as they are unaffected by back
pressure.
The steam trap UNA 3.. consists of a body with bolted
cover and a control unit. Various control units are available
for the steam trap.
The control unit SIMPLEX is a level-dependent float controller
and especially suitable for cold condensate and superheated
steam.
The control unit DUPLEX (UNA 38) is a float controller with
automatic and temperature dependent deaeration facility by
means of a bimetallic air vent. The control unit DUPLEX is
suitable for saturated steam and superheated steam.
The control unit with orifice (O) 80 MAX (UNA 38) is designed for large flowrates and high pressures and available as
SIMPLEX or DUPLEX version.
The control unit with orifice (O) 140 MAX (UNA 39) is a
