Important Notes

Usage for the intended purpose

Use steam traps UNA 14, UNA 16, UNA 16A and air trap UNA 14P only for the discharge of condensate
and liquids.

UNA 14, UNA 16, UNA 16A:

Use the equipment only for the discharge of condensate from steam lines within the specified pressure
and temperature ratings and check the corrosion resistance and chemical suitability for the application
in question.

UNA 14P:

Use the equipment only for the discharge of condensate from compressed air lines or other gas lines
within the specified pressure and temperature ratings and check the corrosion resistance and chemical
suitability for the application in question.

Safety note

The equipment must only be installed by qualified staff.
Qualified staff are those persons who – through adequate training in engineering, the use and
application of equipment in accordance with regulations concerning steam systems, and first aid &
accident prevention – have achieved a recognised level of competence appropriate to the installation
and commissioning of this device.

Danger

The trap is under pressure during operation.
When loosening flanged connections, plugs or the control unit hot water, steam,
corrosive fluids or toxic gases may escape.

This presents the risk of severe scalds and acid burns to the whole body.
Toxic gases may cause severe cases of poisoning.

Before carrying out installation and maintenance work make sure the system is
depressurized.
Isolate the trap from both upstream and downstream pressure.
The trap becomes hot during operation.
This presents the risk of severe burns to hands and arms.
Before carrying out installation and maintenance work make sure that the trap is cold.

Sharp edges on internals present a danger of cuts to hands. Always wear industrial
gloves when replacing the control unit.

Explanatory Notes – continued –

Description

UNA 14, UNA 16, UNA 16A, UNA 14P are steam/air traps with ball float and rolling ball valve. The
steam traps can be used for all operating conditions, as they are unaffected by back pressure. They
consist of a body with bolted cover and a control unit. The control unit is freely accessible after
removing the cover. It can be completely replaced without having to remove the valve body from the
line. A conversion of “h” design to “v” design or vice versa is possible without any problem by
repositioning body and control unit. The direction of flow is indicated by an arrow, the position of
installation by the word “Top” on the name plate.

■ suitable for large condensate flowrates

■ “h”-design for horizontal lines

■ “v”-design for vertical lines

(To convert “h” to “v” design or vice versa turn cover and control unit respectively)

UNA 14, UNA 16, UNA 16A

Three different control units are available: Control unit “SIMPLEX”: level-dependent float control
particularly suitable for cold condensate. Control unit “SIMPLEX R”: level-dependent float control
with internal vent pipe for continuous air-venting. Control unit “DUPLEX”: float control with
temperature-dependent automatic air-venting of saturated steam systems.

UNA 14P

The air trap is suitable for draining compressed air and gas systems. Two different control units are
available: Control unit “SIMPLEX” with steel valve ball or control unit “SIMPLEX P” with Perbunan
valve ball. The air traps feature as standard a manual purging device (float-lifting lever) and a 3/8"
BSP connection (with plug) for subsequent fitting of an air-balance pipe.

Function

®

As the condensate flows into the steam trap it operates the float, which in turn opens the rolling ball
valve of the control unit, and in doing so uncovers the discharge passage. The cross-sectional area
of the orifice dictates the max. flowrate when the discharge passage is completely open. The max.
allowable differential pressure of the control unit used depends on the cross-sectional area of the
orifice and the density of the fluid to be discharged.
Three different orifices are available (retrofitting possible).
Float-operated steam traps equipped with control units DUPLEX enable automatic temperature­dependent deaeration of saturated steam systems at start-up and during continuous operation.
The air trap UNA 14P features an orifice as standard which is rated for a max. differential pressure of
up to 16 bar and a liquid density of

ρ = 1000 kg/m

3

. Note that lower densities reduce the max.
service range accordingly.
The flowrates are indicated in the capacity charts. Air traps for other pressure ratings are available
on request.

Installation

UNA 14, UNA 16, UNA 16A, UNA 14P

Float-operated steam traps can – depending on the design of the trap body – be installed in
horizontal or vertical lines with downward flow. Conversion to obtain a different flow direction
is possible:

Flanged design

1. Observe position of installation. The name plate E must always be on top.

2. Observe the direction of flow. The arrow indicating the flow direction A is on the trap body.
Change direction of flow of UNA 14, UNA 16, UNA 16A or UNA 14P if necessary.

3. Consider space required for opening trap. When the trap is installed a minimum space of at least
120 mm is required for removing the cover I!

4. Remove plastic plugs. They are only used as transit protection.

5. Clean seating surfaces of both flange faces.

6. Install trap.

Butt-weld design

1. Observe position of installation. The name plate E must always be on top.

2. Observe the direction of flow. The arrow indicating the flow direction A is on the trap body.
Change direction of flow of UNA 16 if necessary.

3. Consider space required for opening trap. When the trap is installed a minimum space of at least
120 mm is required for removing the cover I!

4. Remove plastic plugs. They are only used as transit protection.

Attention

■ Only qualified welders certified e. g. according to DIN EN 287 may weld the steam

trap into pressurized lines.

14

Heat treatment of welds

A subsequent heat treatment of the welds is not required.

Change direction of flow

1. Remove cover I from body B, fig. 3

2. Lever control unit LMN off its support using a screwdriver, fig. 4

3. Turn body so that the arrow A points in the desired flow direction.

4. Position control unit on support and fix it by sharp blows, fig. 5

5. Clean seating surfaces of body and cover.

6. Apply heat-resistant lubricant to seating surface or cover and threads of fixing screws
(use for instance WINIX

®

2150).

7. Insert a new gasket O and put cover onto trap body. Tighten body screws P in diagonally
opposite pairs to a torque of 35 Nm. Retighten screws after the commissioning procedure.

Tools

■ Hexagon-type offset screwdriver (Allen key), size 8 to DIN 911L

■ Screwdriver (5.5/125), DIN 5265

■ Punch (120/10), DIN 7250

■ Hammer (500 /10), DIN 1041

Air balance pipe

For GESTRA air traps UNA 14P we recommend the installation of an air balance pipe K in order to
equilize the pressure. The air balance pipe ensures a continuous condensate flow from the fluid line
to the trap and effectively prevents the formation of water pockets.

Unfavourable piping geometries and certain positions of installation may also require the installation
of an air balance pipe for steam traps. The air balance pipe effectively prevents the formation of
water pockets.

Maintenance

GESTRA steam traps UNA 14, UNA 16, UNA 16A do not require any special maintenance. However,
if used in new installations which have not been rinsed it may be necessary to check and clean the
trap.

The GESTRA air trap UNA 14P does not require any special maintenance. If, however, the trap is
used with very oily condensate we recommend to clean the trap at regular intervals or to install an
oil separator upstream of the trap.
