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 device (see Figures 5 and 7) activates the VSX4 and VSX8 Series controller�

The pressure measuring element of the VSX4 and VSX8 Series controller consists of a diaphragm that senses downstream pressure� The

downstream pressure is controlled by the regulator

(Figure 7)� The top side of the VSX4 and VSX8 Series

diaphragm encounters the force imposed by the overpressure shut-o󰀨 spring and underpressure shut-o󰀨 spring.

When the downstream pressure increases above the

overpressure shut-o󰀨 (OPSO) setting, the diaphragm

moves up�

When the downstream pressure decreases below the

underpressure shut-o󰀨 (UPSO) setting, the diaphragm

moves down�

Both of these actions result in the rotation of the cam

and the release of the reset pin�

The valve plug spring moves the valve plug against

the regulator port, stopping the ow of gas.

Before opening the valve plug, an equal pressure

balance on inlet and outlet sides is required�

Figure 4. Nameplate for explosive atmosphere if ATEX assembled

Refer to the VSX4 and VSX8 Series Instruction Manual, Form 5867� Using the reset button, activate

the internal bypass, then rearm the valve plug in

accordance with the Manual Reset Procedure� Rearming and pressure balancing are achieved at the same time�

Installation and Overpressure Protection

Personal injury or system damage

may result if this slam-shut device is installed, without appropriate overpressure protection, where service conditions could exceed the limits

given on the Specications section and

slam- shut device nameplate.

All vents should be kept open to permit

free ow of gas to the atmosphere. 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 and of

the slam-shut device downward to allow condensate to drain. This minimizes the

possibility of freezing and accumulation of water or other foreign materials entering the vent and interfering with

proper operation.

Slam-shut device installations should be adequately protected from

physical damage.

The equipment should not receive any

type of shock causing damage to the casing and therefore causing leaks.

No modication should be made to the structure of the equipment (drilling, grinding and 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 the regulator/slam-shut device to

the outdoors.

Failure to install a downstream control line could result in a hazardous condition. A downstream control line is required for the VS100 Series installation. The slam-shut device will

not control pressure or shuto󰀨 if a

downstream control line is not installed.

If the slam-shut device is exposed to an overpressure condition, it should be

inspected for any damage that may have

occurred. Slam-shut device operation

below the limits specied in the Specications section and slam- shut

device nameplate does not preclude

the possibility of damage from external

sources or from debris in the pipeline.

The usage of an assembly incorporating

an electrical accessory in an explosive

atmosphere the VS100 Series regulators

(proxy, microswitch) are:

– are classied “assembly”

in conformity with the

ATEX Directive 2014/34/EU (ref CEN/SFG-I Guidance sheet

-February 2015)

– can be installed in any type of

classied zones according to

the Directive 1999/92/EC dated

16 December 1999, according to the following conditions:
