Regulator relief valve protects low pressure downstreamcomponents if delivery pressure exceeds gauge maximum pressure.

Enables reliable, flexible connection to gas cylinder valve, permitting vertical adjustment of ± 50 mm. Pigtail design andconfiguration is specific for each gas.

Stainless steel 0.4µ high pressure pre filter protects systemcomponents from contamination and damage by paniculatematter.

2-way, 3-port valve isolates regulator and low-pressure side ofmanifold from purge gas during purging operations.

Ventilates process gas from high pressure side of manifold duringpurging operations and in emergencies.

Used during cylinder change to enable ventilation of process gasat reduced pressure. Also enables maintenance purge ofregulator and downstream process lines.

This valve isolates gas panel from downstream processequipment. Enables manifold and regulator to be purged withoutcontamination of downstream process gas lines.

Prevents backflow of gases into gas panel.

Controls flow of purge gas into pigtail and manifold duringpurging. Check valve prevents backflow of process gas to purgegas source.

Pneumatically operated, normally closed valve enables manualshutdown of process gas flow. ESO valve is typically actuated byan IGS gas monitor (Model GM-1 or GM-6), automatically shuttingoff gas in case of excess flow, exhaust system failure, fire or iftoxic gas is detected. (Option)

Shuts off flow by sending a signal to an IGS Gas Monitor(GB 6), which then closes the ESO valve. (Option)

2 Valve System for Non-Reactive Process or Purge Gas

The 2 valve self-purging manifold istypically used to control nitrogen orother self-purging gases. Thismanifold enables removal of atmosphere trapped between thecylinder connection and regulator bypressurizing through the cylindervalve and venting through the thehigh-pressure vent (HPV) valve.

Pre-filter is optional

Suggested ApplicationPurge N2 Ar He

3 Valve System for Non-Reactive Process Gases

The 3 Valve self-purge manifold issimilar to the 2-valve system, butwith the addition of process isolationvalve (PLI). This valve isolates theprocess line and thus enablesmanifold maintenance to take placewithout Introducing atmospheredown the process line.

3 Valve Purgeable System for Ozone depletingand skin irritating Gases

4 Valve ESO system for Hazardous Gas Mixtures

The 3 valve purgeable manifold issimilar to the 2 valve self purge, butwith a purge gas inlet valve added toallow inert purge on high pressureside and pigtail.

Typically used to control Freons orother skin irritating gases enablesremoval and purging of trappedgases between the cylinderconnection and regulator bypressurizing through the purge gasvalve and venting through the high-pressure vent valve (HPV).

Suggested ApplicationN2O O2 – Freons

The 4-valve ESO is a purgeable system with Emergency shut offvalve, and 2 valve protection duringcylinder change over.

Specific Features

Emergency ShutdownSwitch

Open Valve Switch

Horn Silence Switch

Alarm Reset Switch

Service/Purge Switch(Option)

The large red button closes the solenoid valve, venting the pneu-matic supply to the fail safe, normally closed pneumatic valve,and thus shutting the ESO. This stops the process gas flow.

This button energises the solenoid valve which directs air to thenormally closed, pneumatic valve, this opens the ESO and allowsprocess gas to flow through the manifold.

This black button stops the flashing alarm indicator LEDs andsilences audible alarm.

This black button resets alarms only when detected condition no longer exists.

Positioning the toggle switch to Purge disables “Remote Start”function and detection of “Excess Flow”, and “High RegulatorDelivery Pressure” so purging can be accomplished withouttriggering shutdown. SERVICE/PURGE switch should be activatedonly during purging or maintenance. Cabinet exhaust and remoteshut down input remain active.

Green LED Indicators (normal operation)

GB6

POWER remains lit whenever monitor is in operation. Indicates line power is on.

VALVE OPEN remains lit when its control solenoid is energised allowing process gas toflow through the manifold.

ALARM flashes when change in monitored condition is detected. May be used for anysensor input.

HIGH DELIVERY PRESS flashes when regulator delivery pressure gauge exceeds pre-set pressure limit.

EXCESS FLOW flashes when maximum flow rate is exceeded. A six second time delayprevents unnecessary emergency shutdown caused by a momentary gas flow surge.

EXHAUST FAIL flashes when flow of exhaust air through cylinder cabinet has beeninterrupted.

FIRE flashes when fire alarm occurs

REMOTE SHUTDOWN flashes when remotely-located momentary contact shutdownswitch has been activated.

GAS LEAK flashes when gas leak is detected

LOW CYLINDER flashes when gas pressure in cylinder is below established minimum.

PURGE MODE flashes when SERVICE/PURGE toggle switch is set to purge mode.(Option)

Red LED Indicators (emergency or shutdown condition)
