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.

Type OSE

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).

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 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.

• Bleed off inlet pressure

• Unscrew impulse connection IS

• Remove BM cover (key 8)

• Unscrew fastening screw (key 9)

• Remove cap

• Remove BM

• Unscrew screws (key 10)

The removal of the oriﬁce (not recommended) requires a

special extraction tool

Reassembly

• Perform the above operations in reverse order (respect

tightening torques)

• Replace O-rings at each disassembly

• The valve plug should be maintained in an upright position

using the packing gland to facilitate it’s removal

Type OSE

• Precaution should be taken when removing or replacing

the valve plug to avoid damaging the segments
