INTRODUCTION
Scope of Manual
This manual provides installation, start-up, maintenance,
and parts ordering information for the Type OSE Slam-
Shut Valve.
Information on other equipment used with this slam-shut
valve is found in separate manuals.
Product Description
The OSE Slam-Shut Valve protects transmission and
distribution networks or pipe lines supplying industries and
commercial businesses.
It permits the gas flow to be cut off rapidly and totally in the
case of under or over regulator pressure.
The OSE exists in DN 25 (1”) to DN 150 (6”). DN 200 (8”)
and DN 250 (10”) are covered by the OSE LS.
The OSE consists of:
• A body with a removable orifice, enclosed by a bonnet
• A valve plug with integral bypass, tightshut by an O-ring
• A release relay type OS2 including:
- A mechanism box (BM)
- A safety manometric box (BMS) to be connected on
the outlet side of the pressure regulator.

OPERATION
The pressure of the zone to be protected (generally the pipe
line on the outlet side of the pressure regulator and situated
after the slam shut valve) activates the safety manometric
box BMS.
If pressure rises above the release set point the release
relay frees the valve plug (key 7).
Through the action of the weight of the valve plug, the
closing spring and the fluid (attempting to close), the valve
plug will seat into the orifice (key 6).
The gas flow is obstructed until the mechanism box is
manually rearmed.
To reopen the valve plug an equal pressure balance on inlet
and outlet sides is required.
The mechanism box is rearmed after opening the internal
bypass (key 1).
Rearming and balancing are achieved at the same time.
INSTALLATION
!
AVERTISSEMENTS
All interventions on the equipment should
only be performed by qualified and
trained personnel.
C51
Figure 4. Type OSE LS - Principle of Operation
The slam shut valve is installed on the
inlet side of the regulator, on the horizontal
pipeline. The mechanism box should be
situated on top (see above schematic) or on
top for versions DN 25-50-80.
Installation according to EN12186 is recommended.
Install according to direction of the fluid flow
(see arrow).
When assembling with adjacent elements,
care must be taken not to create pressure
force on the body and the assembling
elements (bolts, O-rings, flanges) should be
compatible with the geometry and working
conditions of the equipment.
If the case arises a support must be used to
avoid pressure force on the body (a support
can be installed under the flanges).
Connect the safety manometric box (IS) to
the impulse at 4D on the outlet pipe.
It is recommended to install an isolation
valve (R1) and an atmospheric valve (R2), which
can be useful for tripping and verifications.
No modification should be made to the
structure of the equipment (drilling, grinding,
soldering ...).
Verify that the inlet side is protected by an
appropriate device(s) to avoid exceeding the
limits of utilization (PS, TS).

Verify that the limits of utilization correspond
to the appropriate operating conditions.
Verify that the safety manometric box (BMS)
and spring correspond to the appropriate
operating conditions on the outlet side of the
regulator.
The equipment should not receive any type
of shock, especially the release relay.
The user should verify or carry out a
protection adapted to the environment.
Fire, seismic and lightening are not taken
into consideration for standard regulators.
If required, a special product selection and/
or specific calculations may be supplied
according to specific requirements.
If the slam-shut is classified under operating
class B the BMS diaphragm should be
checked periodically.
