1. DESCRIPTION

The SG series gate valve is unidire tional flanges type valve designed for general industry servi e appli ations

(spe ially, but not only, for dust handling appli ations). The design of body, seat and obturator assures non-

logging shut-off with solids.

The SG series omplies with the following European dire tives:

-2006/42/EC: Ma hinery Dire tive.

When appli able it an also omply with the following additional dire tives:

-2014/68/EU: Pressure Equipment Dire tive.

-2014/34/EU: Potentially Explosive Atmospheres (ATEX).

The SG valve may omply with the dire tive regarding equipment and prote tive systems for their use

in explosive atmospheres. In these ases, the logotype shall appear on the identifi ation label of the

valve. This label shows the exa t lassifi ation of the zone where the valve an be used. The user will

be liable for its use in any other zone.

This dire tive only applies in the following atmospheri onditions:

•0,8 bar ≤ P ≤ 1,2 bar.

•-20 °C ≤T ≤ 60 °C.

Any in rease in temperature due to fri tional warmth is negligible, sin e the relative speed of the

moving parts is extremely low.

The risk analysis asso iated to this dire tive does not take into a ount the fluid that goes through the

valve, even when su h fluid produ es an explosive atmosphere. The user must take into a ount the

risks that the fluid generates, su h as:

•Heating of the valve surfa e.

•Generation of ele trostati harges aused by displa ement of the fluid.

•Sho k waves aused by the installation (water hammer), internal rashes generated by the

pellets or the risks due to foreign bodies sus eptible of being present in the installation.

2. HANDLING

The valves are pa ked a ording to the appropriate transport standards. If you re eive the pa king damaged,

please inform the transport ompany in writing and onta t you ORBINOX representative.

When handling an ORBINOX valve please pay attention to the following points:

•Do NOT atta h lifting gear to the valve a tuators or gate guards

Do NOT atta h lifting gear to the valve a tuators or gate guardsDo NOT atta h lifting gear to the valve a tuators or gate guards

Do NOT atta h lifting gear to the valve a tuators or gate guards. They are not designed to

bear the weight and ould easily be damaged.

•Do NOT lift the valve by the valve bore

Do NOT lift the valve by the valve boreDo NOT lift the valve by the valve bore

Do NOT lift the valve by the valve bore. This an ause damage to the seating surfa es and

seals.

•Che k that sele ted lifting gear is rated to arry the weight of the valve.

•The valve an be handled using eyebolts, soft straps or slings.

•Eyebolts: make sure the eyebolts have the same thread as the boltholes and they are all well

se ured. Ideally when using lifting gear to move an ORBINOX valve, it should be supported by

two or more eyebolts s rewed into the tapped fixing holes in the valve body.

•Soft straps: with the valve in the losed position, the straps should be pla ed between the gland

area and the bore su h that the valve is balan ed.

3. INSTALLATION

To avoid any personal injury or damage to property from the release of pro ess fluid:

•Those in harge of handling and maintenan e of the valve must be qualified and trained in

valve operations.

•Use appropriate personal prote tion equipment (gloves, safety shoes, et ).

•Shut off all operating lines to the valve and pla e a warning sign.

•Isolate the valve ompletely from the pro ess.

•Release pro ess pressure.

•Drain the pro ess fluid from the valve.

•The valve must be properly earthed.

These instru tions must be observed when installing an ORBINOX valve in an ATEX zone:

•Make sure the valve is ATEX marked a ording the requested zone and it in ludes all anti-

stati devi es.

•Che k ontinuity between the valve body and the pipe (test in a ordan e with EN 12266-2

Test F21 Annex B, §B.2.2.2 and §B.2.3.1).

•The above he k must be done every time the valve has been removed from the line, servi ed

and put ba k to the line.

Before installation, inspe t the valve body and omponents for any damage that may have o urred during

shipping or storage. Make sure the internal avities within the valve body are lean. Inspe t the pipeline and

mating flanges, making sure the pipe is free of foreign material and that the flanges are lean.

The valve is unidire tional. It should be installed with pressure exerted against the seat. The words “SEAT SIDE”

are marked on the valve body to indi ate the position of the valve seat. Installation and the orre t orientation with

respe t to the dire tion of the flow is the responsibility of the user.

Spe ial are should be taken to maintain the orre t distan e between the flanges and to ensure that they are

parallel to the valve body. In orre t alignment of the valve an ause deformations, whi h an lead to diffi ulties in

operation.

The valve an be mounted in any position regarding the pipe. However, it is advisable to pla e it horizontally in

verti al if the installation allows it.

On e the valve is installed, test that the flanges have been fastened orre tly and that all ele tri al and/or

pneumati onne tions have been properly made.

The operation of automated valves is limited only with fitted gate overs to fulfil 2006/42/EC

(Ma hinery Dire tive).

First, operate the valve with no flow in the pipeline. Then test operation and valve seal with flow. On e

performan e has been tested, the valve an be put into operation.

4. ACTUATORS

The operation of automated valves is limited only with fitted gate overs to fulfil 2006/42/EC

(Ma hinery Dire tive).

•Allowed a tuators for ATEX zones: Hand wheel, Chain wheel, Bevel Gear, Lever, Pneumati

Double A ting, Hydrauli and Ele tri al motor.

•Make sure that the a tuator is marked a ording for the requested zone.

•Maximum rotating speed is 10 rpm.

4.1. HANDWHEEL

Turn the hand wheel anti lo kwise to open the valve. Turn the hand wheel lo kwise to lose the valve.

4.2. LEVER

To operate the valve with this devi e, first loosen the lo king lamp. Then either open or lose the valve by moving

the lever in the desired dire tion. Finally, fix the position of the lever with the lo king lamp.

4.3. PNEUMATIC

Valves are usually supplied with a double a ting pneumati a tuator although, upon request, we an supply

single-a ting a tuators (be ation about limitations of single a ting a tuators in ATEX zones). In either ase the

feed pressure an vary between 3,5 bar and 8 bar. Unless otherwise spe ified the a tuator has been sized with a

supply pressure of 6 bar.

It is essential for a good maintenan e of the ylinder that air should be well dried, filtered and lubri ated. Air

quality shall fulfil the following requirements:

•ISO 8573-1 Grade 5:4:3 for regular pro ess (ON / OFF servi es).

•ISO 8573-1 Grade 5:3:3 for regular pro ess at low temperature (-20 °C).

It is re ommended to a tuate the ylinder 3-4 times before the start up on e it is installed in the pipeline.

4.4. ELECTRIC ACTUATOR

Depending on the type or brand of the ele tri a tuator, spe ifi instru tions (i.e. a manufa turer’s manual) will be

supplied.

5. MAINTENANCE

The valve must not undergo any modifi ations without a previous agreement with ORBINOX.

ORBINOX shall not be liable for any damages that may arise due to the use of non-original parts or omponents.

To avoid any personal injury or damage to property from the release of pro ess fluid:

•Those in harge of handling and maintenan e of the valve must be qualified and trained in

valve operations.

•Use appropriate personal prote tion equipment (gloves, safety shoes, et ).

•Shut off all operating lines to the valve and pla e a warning sign.

•Isolate the valve ompletely from the pro ess.

•Release pro ess pressure.

•Drain the pro ess fluid from the valve.

•The valve must be properly earthed.

These instru tions must be observed when installing an ORBINOX valve in an ATEX zone:

•The maintenan e personnel must be made fully aware of the risks of explosion, and it is

advisable that they re eive spe ifi training regarding ATEX.

•A ording to EN 13463-1 (15), during installation and maintenan e operations, use hand

tools (non-ele tri ) with Working Allowan e.

•Periodi ity of he k and evaluation of valve ele tri al ondu tivity must be determined by end

user a ording to valve working onditions. In any ase, on e the valve is put into operation,

the pa king area must be revised after the valve has been stroked 100 times or after 3 months

of operation, whatever happens first. After this preliminary he k, new he king periods must

be determined by end user based on the results of this first he k

•Clean the valve periodi ally to prevent dust a umulation. Do not sweep or dump the dust.

Always use a va uum leaner system.

•Do not apply any new oating to the valve. Should it require new oating, please onta t our

losest representative.

•Allowed seals: EPDM, VITON, NITRILE, GRAPHITE, SILICONE, PTFE and METAL (no seal).

•Any other materials but those above are not allowed to be used in ATEX zones.
