Figure 4. Typical VS100 Operational Schematic

Principle of Operation
The pressure in the zone to be protected (generally
the pipeline on the outlet side of the pressure regulator
and situated after the slam shut (see Figures 4 and 6)
activates the slam-shut device VSX4 Series.
The pressure measuring element of the VSX4 Seriesslam-shut device consists of a diaphragm that senses
downstream pressure. The downstream pressure iscontrolled by the regulator (Figure 6). The top side ofthe diaphragm encounters the force imposed by the
overpressure shut-off spring and underpressure
shut-off spring.
When the downstream pressure increases above theoverpressure shut-off (OPSO) setting, the diaphragmmoves up.
4

When the downstream pressure decreases below
the underpressure shut-off (UPSO) setting, thediaphragm moves down.
Both of these actions result in the rotation of the camand the release of the reset pin.
The valve plug spring moves the valve plug against
the regulator port, stopping the flow of gas.
Before opening the valve plug, an equal pressurebalance on inlet and outlet sides is required.
Using the reset button, activate the internal bypass,then rearm the valve plug in accordance with the
VSX4 Series instruction manual. Rearming andbalancing are achieved at the same time.

Installation and Overpressure
Protection!

WARNING

Personal injury or system damage
may result if this slam shut isinstalled, without appropriate
overpressure protection, whereservice conditions could exceed thelimits given on the Specifications
section and slam shut nameplate.
All vents should be kept open
to permit free flow of gas to theatmosphere. Protect openings
against entrance of rain, snow,
insects or any other foreign material
that may plug the vent or vent line.
When installing outdoors, point the
spring case vent of the regulator andof the slam-shut device downward
to allow condensate to drain. This
minimizes the possibility of freezing
and accumulation of water or otherforeign materials entering the ventand interfering with proper operation.
Slam-shut device installations
should be adequately protected fromphysical damage.
The equipment should not receive any
type of shock causing damage to thecasing and therefore causing leaks.

6

No modification should be made to thestructure of the equipment (drilling,
grinding, soldering...).
Under enclosed conditions or
indoors, escaping gas may
accumulate and be an explosion
hazard. In these cases, the vent(s)should be piped away from theregulator/slam-shut device tothe outdoors.
Failure to install a downstream control
line could result in a hazardous
condition. Install downstream controlline(s) to the slam-shut device whenconstruction uses external pressure
registration. The regulator andslam-shut device will not control
pressure or shutoff if a downstream
control line is not installed on those
constructions where external pressure
registration is required.
If the slam-shut device is exposed toan overpressure condition, it should
be inspected for any damage that may
have occurred. Slam-shut device
operation below the limits specified in
the Specifications section andslam shut nameplate does not preclude
the possibility of damage from externalsources or from debris in the pipeline.

Type VS100
