INTRODUCTION
Scope of the 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
Type
OSE Slam‑Shut Valve protects transmission and distribution networks or pipe lines supplying industries and commercial businesses.
It permits the gas ow to be cut off rapidly and totally in the
case of under or over regulator pressure.
The Type OSE exists in DN 25 (1”) to DN 150 (6”). DN 200 (8”) and DN 250 (10”) are covered by the Type OSE LS.
The Type OSE consists of:
• A body with a removable orice, 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 uid (attempting to close), the valve plug will seat into the orice (key 6).
The gas ow 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
!
WARNING
All interventions on the equipment should
only be performed by qualied 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 uid ow (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, anges) 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 anges).
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 verications.
No modication 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).

Figure 5. Type OSE Slam-Shut Valve Installation Schematic
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 specic calculations may be supplied according to specic requirements.
If the slam-shut is classied under operating
class B the
BMS diaphragm should be
checked periodically.
