1. ERIKS operating companies
ECON ball valves are being delivered by several ERIKS operating companies on a worldwide
basis. In this manual these will be referred to as ‘ERIKS’, the individual terms of delivery of the
ERIKS operating company having executed the order are applicable.
2. Product description
The ECON ball valves are designed according the information in our latest catalogue or see our
website www.eriks.com and should be used in accordance with the applicable pressure-
temperature rating as stated on this website. Ball valves are provided with marking, according to
EN 19. The marking makes the identification of the valve easier and contains:
- size (inch)
- pressure rating class
- body material marking
- ECON logo
- heat numbers
3. Requirements for maintenance staff
The staff assigned to do assembly, operating and maintenance tasks should be qualified to carry
out such jobs and in any circumstance, ensure personal safety
4. Transport and storage
During transport and storage the valves should be protected against external forces, influence and
destruction of the painting layer as well. The purpose of the painting layer is to protect the valve
against rust, during transport and storage. The valves should be stored in an unpolluted space
and should also be protected against all atmospheric circumstances. There should be taken care
of the temperature and humidity in the room, in order to prevent condensate formation.
5. Function
ECON ball valves are designed to stop the flow of a medium. The valve is closed by turning the
lever clockwise; please don’t use tools to increase the torque on the lever.
6. Application
The ECON ball valves are used for industrial systems gasses and liquids. The valves are
designed for standard operating conditions. For the use of extreme conditions e.g. aggressive or
abrasive media, it is recommended to mention this at the ordering stage, to verify whether the
valve is suitable. The installation designer is responsible for the valve selection, suitable for the
working conditions. The valves are unsuitable, without written permission of an ERIKS company,
to apply for hazardous media as referred into Regulation (EC) No 1272/2008..

7. Installation
a. Remove the protective plastic cap on 2-threaded, BW and SW ends, and clean or flush the
valves.
b. Prior to mounting, flush and/or clean the pipeline to remove all accumulated extraneous
matters, which may damage the seats and ball surface and check if the valve has a preferred
flow direction and take this direction into account during installation.
c. Installation of threaded ends:
Use conventional sealant (e.g. Teflon) on the threads.
Apply a wrench only on the end cap of the valve for tightening. Applying a wrench on
the valve body or lever can seriously damage the valve.
d. Installation of BW and SW end valves
Tack-weld the valve on the pipe on four points on both caps, with the ball valve in
open position. Extended butt-weld end ball valves allow direct welding. For short butt-
weld or socket-weld end connections process the next steps.
Removed all body bolts except one and after losing the remaining one, the valve body
can be swung out. Secure seats from falling temporary with tape.
Finish welding both end caps on the pipe.
When cooled down, clean both end caps and body surface.
Remove temporary tape, swing the body back to the original position and replace the
bolts (if necessary). Put the valve in the open position. Tighten all nuts slightly. During
this operation it is very important to keep body and end caps perfectly parallel, thus,
preventing distortion of the end caps.
Tighten body bolts evenly. Make sure that maximum tightening torque is observed per
bolting torque data. See table B
e. Check proper operation of the valve.
f. The pipeline shall be free of tension after installation.
g. For any further information please contact the ERIKS company that has supplied the valves.
Contact information can be found on www.eriks.com
h. Make sure the pipeline will be flushed clean prior to operation.
i. The operation of the valve consist of turning the stem (by manual or automated means) ¼ turn
(900) clockwise to close, and ¼ turn counter-clockwise to open.
j. When the lever (if used) and/or stem flats or groove are in line with the pipeline, the valve is
open.
k. Besides operating by lever, Fig. 7422, 7442, 7522, 7542, 7622, 7642, 7722 and 7742 can also
be operated with an actuator, mounted on the ISO 5211 “Direct Mount” top-flange. (Please
see our catalogue to check top-flanges sizes)
l. Operating torque requirements will vary depending on the length of time between cycle, media
in the system line pressure and type of valve seat.
8. Maintenance
Long life and maintenance-free of valves can be maintained under normal working conditions and
in accordance with pressure/temperature and compatibility data chart.
Warning:
Before starting any service jobs, make sure that the medium supply to the pipeline is cut
off, pressure is decreased to ambient pressure, the pipeline is completely cleaned and
ventilated and the plant is cooled down.
Keep always personal safety precautions in mind and always use appropriate protection
e.g. clothing, masks, gloves etc.
Be alert that ball valves can trap pressurized fluid in ball cavity when closed position.
Be alert that the temperature still can be very high of low and can cause burns.

a. Re-tighten Packing
For maximum stem packing life, the proper packing adjustment procedure must be followed:
Should a leakage occur at the stem packing, retighten the stem nut (8)
Take care that the stem nut (8) is not tighten too much. Normally the leakage can be
stopped by simply turning the stem nut (8) by 30° to 60° clockwise.
b. Replacement of seats and seals
1) Disassembly of parts can be done while the valve is installed in the pipeline:
Before disassembly, make sure the pressure is released, to discharge any hazardous
media from the valve inside body cavity and to cool down the ball valve.
Remove all body bolts and washers (15+16) except one and after losing the remaining
one, the valve body can be swung out, and place valve in close position.
To swing the body can only be done at the Non Fire-Safe executions!!
Remove body gasket (5), seat rings (4) and ball (3). Inspect the ball accurately on
scratches, if any, the ball should be replaced.
When the stem packing needs to be replaced. Remove parts of upper parts in following
order: Lever nut/screw (19+20), lever (18), nut-lock-cap (7), stem nut (8), Belleville
washers (9) and gland (10).
Push stem (6) down into body cavity and remove, then remove upper washer (11B),
stem packing (11A) and lower washer (11B) from the body (1).
Also the O-ring (12) can now be taken out from the stem.
