FEATURES
The 2-way 736 XS (steel) or 746 XS (stainless steel) ball valve + SF is intended for the manual shut-off of networks
for industrial fluids, providing position display and feedback information control. This 3-piece external tie-bolt
ball valve is easy to remove for servicing. This full-bore valve has an anti-static device and double leak-proofing
at the cable gland. It is EC- and ATEX- and TA-LUFT-approved. The SF switch box is equipped, as standard, with 2
dry contacts. Due to its IP67 leak-tightness, it can be installed both indoors and outdoors. Different contacts and
detectors are available as options.

ASSEMBLY AND MAINTAINANCE INSTRUCTIONS
1 - Installation
1.1 - Checks
oCheck that the material of the valve body is chemically compatible with the fluid.
oCheck that the pressure and service conditions are compatible with the (P, T) diagram of the valve. See
§ “Service limits”
oCheck that the fluid is clean and free of particles. The latter could scratch the ball and damage the seats,
hence causing the valve to leak. If need be, install an upstream filter.
oCheck that there is no risk of thermal expansion of the fluid, which could damage the seats. In the open
position, a hole at the top of the ball balances the pressures between the body cavity and the flow of
the fluid. As an option, we recommend a relief hole upstream of the valve for balancing the pressures
for fluids such as ammonia, LPG, chlorine, etc.
oCheck that the valve is not used for flow or pressure control since it is not intended for this use and
there is a risk of premature wear of the seats, in particular in the event of high pressure and/or
temperature. For this special application, preferably use our ‘”V-port” version with a V-shaped hole in
the ball. Please contact us.
oCheck that the valve is not used on a gas which might condense at certain times during the process. In
such a case, the pressure within the body cavity could become negative, which could lead to a significant
deformation of the seats. Please contact us.
oStatic electricity: the valve will be supplied with a ball-stem-body internal electrical continuity tester. If
the service conditions require the electrical continuity of the installation, check its earthing.
oIf the valve is installed in an explosive zone, you must follow the additional “IMEVMATEX” instructions.
1.2 - Storage before installation
oFollow our general “IMESTOCK” instructions for storage.
oCheck that the tie-bolts of the valves were not loosen during transport.
1.3 - Installation
oBefore any installation, isolate the piping upstream and downstream, depressurize the piping and bring
the installation to ambient temperature. Carefully clean the piping of any particle (foreign body, dust,
rust, etc.) or shavings by water rinsing or air blowing.
oFor valves with a size above DN50, plan to use a hoist.
oRemove the protective tips from the valve ends.
oCheck the cleanliness of the internal surfaces of the valve and if need be, clean them.
oDirection of mounting: the valves do not have a preferred direction of mounting, unless a relief hole
was drilled into the ball.
oCheck the perfect alignment and the proper support of the pipe installation upstream and downstream
of the valve. Alignment defects cause mechanical deformations which can block the valve or lead to
leaks at the body gaskets.

oThreaded valve connection:
oCheck that the standards for the valve internal thread and pipe thread are the same.
oCover the pipe threads using a sealing material (tow, PTFE tape, sealing glue, etc.) which is
suitable for the fluid.
oScrew the tube into the valve end clockwise, as shown in the diagram below.
oCheck the sealing of the connection using a suitable test (hydrostatic test or leak detection
spray).
oConnection of weld-on valves:
oRemove the end (items 2) by unscrewing the tie-bolts, and remove the central body.
oWeld each end onto the upstream or downstream pipe, following the alignment of the tie-bolt
holes.
oCool down to the room temperature the welded ends, then put back the central body
complying with the tightening torques shown in the table below.
oCheck the sealing of the connection using a suitable test (hydrostatic test or leak detection
spray).

oHydraulic test of the installation
oValves were tested at the factory at 1.5 x WP.
oIf a hydrostatic test is carried out on the installation, do not exceed the authorised pressure.
2 - Service
oIf a hot fluid flows across the valve, do not touch the valve surface.
oAlways operate the valve slowly and smoothly.
oOpening clockwise, closing anti-clockwise.
3 - Servicing
3.1 - Frequency of servicing
oThe servicing frequency depends upon the use of the valve, of the type of fluid, of its velocity, of its
frequency of operation, of the cycles of rise and fall in pressure and temperature.
oBefore any intervention, isolate the upstream and downstream pipe installation using the valves
provided for this purpose. Depressurize the pipe installation and bring it to ambient temperature.
oIf the lever has to be removed, do that before disassembling the body.
oTo remove the central body, unscrew the tie-bolts symmetrically. Then gently remove the central part
avoiding to drop the ball.
oTo remove the ball from the body, turn the stem by a quarter turn.

3.2 –Inspecting the state of the valve and possible repair
oCheck the state of the ball (Item 4): it has to be clean and unscratched. If the cleaning or polishing is not
possible, replace it (see the § on spare parts).
oCheck the state of the seats (3.1 and 3.2): they must not be deformed, nor scratched, nor worn, or dirty.
Otherwise, replace them with parts from the gasket kit.
oCheck the state of the packing gland (7.8 and 9): no leak should be found at the stem and the rings
should not be excessively worn. If need be, replace the gaskets.
oCheck the state of the body gaskets (6.1 and 6.2). Replace them if necessary.
oReassemble the different parts of the valve, following the tightening torques shown in the table below.
oCheck that the stem manoeuvring is smooth. Perform about ten manoeuvres.

FEATURES
The SF-type switch box is intended for equipping quarter-turn pneumatic actuators and manual valves. It makes
it possible to have an easy, direct view of the valve position and of the feedback information to control. Of robust
construction, it can be installed outdoors. The position indicator provides a very good visual reading of the valve
position. The SF switch box can be equipped with many switches and detectors (see below). The notched cams
can be manually adjusted with great accuracy, and are insensitive to vibrations.
