3 - OPERATION CYCLE OF BLINDING WITH ONIS LINEBLIND
1Drain and depress the pipe with the bleeder ports
2
2.1 The ONIS blind is closed
2.2 The slide gate is in position 1
2.3 CLEAN or CHANGE the GASKETS BEFORE
EACH OPERATION
33.1 Unfasten safety lock
3.2 Rotate the lever or the gear box actuator on
the stop
4 4.1 Handle the lever until the connecting rod
come in contact with the crank shaft.
Important : The lineblind is completely opened
when there is the contact.
Remarks :
The simultaneous rotation of the set of eccentric shafts
actuated by the lever or the gearbox spread the seats in a
continuous parallel manner. Guides prevent any loss of
alignment of the pipe in an open position. The sliding gate is
lifted and guided by the rollers and moves freely without friction
of the seats.
Diameter inferior to 4" : lifting screws only
Diameter superior to 4" : screws and rollers for lifting
5
5.1 Keep the blind opened if it is necessary
Nota : If when we do not keep the lever, it
comes back in a middle position, this is
probably due to stress in the line.
So it is necessary to keep the contact between
the connecting rod and the crank shaft in
order to not damager the O'rings.
5.2 Move the slide to the position 2 until the stop-
plate is in contact with the body
6
6.1 Close the blind,
6.2 Check if the bolt is in a good position
6.3 Check if the bleeder ports are closed (when
applicable).
BEFORE ANY HANDLING :
- Close the upstream and downstream valve
- Decompress between the valves and the ONIS
lineblind
- Clean the visible part of the spectacle plate

4 – RANGE OF USE – ADDITIONNAL PRECAUTIONS
Design conditions
The ONIS lineblind, which you have just acquired, was designed according to the
information you have transmitted to us on the technical specification SOCOMET F03
when you have passed the order.
This ONIS Lineblind has been specifically designed for the pressures, the temperatures
as well as products defined on the data sheet with the order. It is up to the user to verify
the chemical compatibility of gaskets and materials in touch with products.
The maximum and minimum service pressures and temperatures are stamped on
nameplate fixed on the body of the device.
ATTENTION: DO NOT CHANGE SERVICE CONDITIONS BEFORE CHECKING WITH
SOCOMET STAFF COMPATIBILITY OF THE LINEBLIND WITH THE NEW SERVICE
CONDITIONS.
Except specific request transmitted with the order, the lineblind have been designed for
following conditions:
- Device without insulation
- No external pressure
- Ambient temperature between 0°C and 38°C
- Static pressure conditions
Following conditions are not included in standard lineblind design:
- Consequences due to bad weather or natural events (snow, sand, wind,
earthquakes…)
- Decomposition of unstable fluids
- erosion
- hammer pressure reaction
Nota: On standard lineblind, no additional thickness is considered. Some over thickness can
exist on certain lineblind. Please, contact our technical department for more information.
Complementary using precautions
Lineblind equipped with bleeder ports
- Check that the bleeder ports are accessible and connected to the pipes which recover
the waste or enough taken away from the operator to avoid any poisoning.
- When lineblind is used on dangerous media, indicate on using procedure that the pipe
must be flushed and neutralized from media before any operation.
At the time of the delivery, the lineblinds are equipped with stickers, which inform the staff
that the lineblind cannot be use under pressure. Verify regularly that the stickers are still on
lineblind. Pressure jauge can be installed on bleeder ports, to check the absence of pressure
before the operation.

Automated lineblind
- In case of automated movement (spreading of the seats, movement of the slide gate),
VERIFY THE GOOD FIXATION OF THE COVERS (SLIDE GATE + SHAFT
CRANCKS) BEFORE OPERATING THE LINEBLIND IN AUTOMATIC MODE.
- Do not manipulate manually the lineblind without having to stop the automated
components air or electric supply.
Additional points
High pressure
- The ONIS lineblinds have been designed for maximum allowable pressure transmitted
with the order and mentioned on the builder nameplate. It is the responsibility of the
end user to set up safety devices to limit the overtaking of these services conditions.
External fire
- Important: Excepted if the construction of the ONIS lineblind is called "Fire safe blind",
any external fire can generate a leak of media to the atmosphere due to destruction of
essential pieces of the lineblind as gaskets, bushings etc…
In that case the leak could feed the fire.
Additional safety devices
- Except if it is originally provided with it, the ONIS lineblind can be equipped with
accessories which can improve the reliability and safety of use as:
o Protection covers to limit the degradation of gaskets by chock or external
elements
o Safety lock on slide gate position or spreading of the seats in order to forbid
any fortuitous manipulation.
Residual risks
- Opening of the lineblind under pressure, without stop the process or close the valves
upstream and downstream of the lineblind.
- Line not decompressed before opening of the lineblind.
- Closing of the lineblind with the sliding gate which is not in position, and process given
on the way.
- Not closing of the apparatus with a sliding gate in position.
- Deterioration of the bolt or the safety lock, which involves the possibility of opening
the lineblind in an unexpected way.
- Bad maintenance which can prevent the operation of the apparatus in the long term.
- According to the conveyed product which requires an electric continuity, the correct
maintenance between upstream and downstream of the equipotential braids
equipping the lineblind in this case, must be checked to avoid any risk of electric flash.

1 - Replacement of the seals on sliding gate
Seals replacement is performed without dismantling the sliding gate.
Before any operation :
- Extract the seal with a flat little screwdriver
- Clean the groove
A - Elastomere gaskets
(Neoprene® - Viton® - Perbunan® - EPT®)
- Slightly grease the seal (except in case of oxygen
transportation)
- Insert the new seal into the groove with pushing with
yours fingers then displace your fingers from a
quarter of length further,
- keep on that way, making sure you do not create
bigger loops. (see method under)
B – Elastomere gaskets with PTFE overlay (PTFE or PFA
coated seals)
(coating type : Viton®, silicone, stainless steel)
- Put the PFTE coated seal in boiling water for 15mn.
- Oil the seal before installation in the groove ; insert the seal in the groove as described further
up.
C - Graphite seals with stainless steel inserts (ON 250)
- Place a new seal in the groove with stainless steel insert on the outside ; Push the sliding gate
between the bodies of the lineblind, maintaining the seal with your fingers.
- Tighten the device.
Take out the old gasket (it is not reusable)
It is better to change only the gasket that it has to be changed
Clean out the slide groove completely before installing the new gasket
Put the new gasket into the groove very firmly (max height above the slide = 1/16 inch. or 0.8 mm),
pay attention to the anti-extrusion metallic plates and make sure they are not down in the groove.
Anti-extrusion plates
Spread the seats completely, move the slide gate to insert the new gasket between the seats,
Clamp the seats in order to compress correctly the gasket into the groove ;
If it is necessary to change 2 gaskets, let the first one compressed during an hour if possible
Repeat this operation for the 2nd gasket.
D - Graphite seals type ON 000
Same steps as the ON 250 gasket described above.
There is no stainless steel inserts.
To ensure perfect sealing, check seal condition before any operation.

2- Lubrification on an ONIS Lineblind
- In aggressive environment, cover the shafts with grease to avoid
corrosion. It is only required, once a year, to pour liquid oil on the shaft at
the ring level and to operate the ONIS lineblind to allow dispersion. Use of
greasing spray is recommended.
Lineblinds with mechanical control
- Once a year, carefully check the oil or grease level for the ONIS lineblinds
with gearbox (see manufacturer file attached paragraph B-5)– check also
the vent position (to be located on the upper section) if there is one.
Lineblinds adapted to high temperature
- Fitted with rings with grease injection ports, inject special high
temperature grease once a year through the ring ports.

C - Storage
The ONIS devices must be stored with care in a warehouse, protected from weather aggressions, until
their installation. When stored on site, they must be isolated from the ground and covered. In that
case, the storage period should be as short as possible.
The end blinds and protection plugs should be removed at the last moment during the installation of
the ONIS lineblind on the pipe.
The ONIS lineblind should be kept in a complete open position until their installation. Piping should be
carefully cleaned preferably with compressed air to eliminate any particles. The cleaning of the piping
should be carried out with non corrosive fluids (pure or carbonated water) and followed by compressed
air drying.
Before any operation with the ONIS lineblind, clean the sliding gate and the external seals. It is only
after the piping cleaning and the complete drainage of cleaning fluid that the ONIS lineblind can be
operated.
