Description
UNA 45 MAX, UNA 46 MAX and UNA 46A MAX are items of
equipment for the steam process designed for the effective
removal of condensate from steam.
The ball float opens the orifice as a function of the liquid level.
A rising level results in a proportional opening of the equipment.
The max. discharge capacity depends on the size of the fully
open orifice (O).
As the float rises with the liquid level it pulls the nozzle stem off
the pilot valve, allowing a small amount of fluid to flow through
the pilot valve.
The fluid compresses the bellows of the control unit and, as a
consequence, the discharge orifice is completely uncovered.
Equipment with control unit SIMPLEX is particularly suitable for
cold condensates and superheated steam.
Equipment with control unit DUPLEX may also be used for air
venting the installation. The control unit DUPLEX consists of a float
and a temperature dependent air-venting facility. The air venting
is controlled by the membrane regulator. Equipment with this type
of control unit is particularly suitable for saturated steam systems.
Do not expose the membrane regulator capsule of the DUPLEX
control unit to superheat conditions above 5 K.
The optional float-lifting lever allows you to lift the float manually.
The optional hand-vent valve allows you to air vent the pipe
manually.
The equipment must only be used within the allowable pressure
and temperature limits and only if the chemical and corrosive
influences on the equipment are taken into account.
