1 – GENERAL REQUIREMENT FOR INSTALLATION
- Reduce pipe stress to a minimum
- Take care of flange alignment
- Install the ONIS lineblind in tight position (seats in clamped position)
- Check that clearance between flanges is equivalent to the flange to flange dimension of
the ONIS Lineblind + 2 times the thickness of a flange's gasket.
- Keep flexibility for one of the two pipes to permit to clamp and spread the seats of the ONIS
with an useless effort.
- Put the vent position on upper position when the gear box is equipped with
- Check the oil level for ONIS lineblind with gearbox control .
Before operation
- The sealing of the ONIS lineblind is ensured by seal contact on metallic
surface. It is consequently essential that these two elements are not
damaged prior to their installation.
- The ONIS lineblind is supplied with the sliding gate in open position, the
flanges or weld necks are fitted with blinds or protection plugs to
safeguard the extremities as well as the inner parts.

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
- Check the seals condition.

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.
