Pressure control for protection of public buildings, schools, theaters, hospitals etc.

Installing this kind of regulators provides automatic protection against possible extreme variations in either inlet or outlet gas pressure.

--TECHNICAL DATA

Gas type: Gases of three families: manufactured gas (town gas); natural gase (group H - methane); liquefied petroleum gas, (LPG); non-aggressive gas.

Operational pressure range:

Max. Inlet: 8bar         Outlet Pressure range: 15 to 80 mbar Working temperature range:-15°C--+60°C

Valve Body: Aluminium alloy      Seals: NBR

Operation: By tensioning the spring, without auxiliary energy.

compensation of inlet pressure, standard-supply safety diaphragm, internal pipe impulse.

SETTING

The outlet pressure can be set by means of the set-screw ; by turning clockwise this set-screw the pressure is increased and by turning it anti-clockwise the pressure is decreased.

The pipe fittings located upstream and downstream the regulator allow the reading of the relative pressures, passing from one family of gas to another, choosing the most suitable spring and adjusting the set-screw.

The stabilized pressure should be checked with a pressure gauge. After setting replace the upper cap .

INSTALLATION

Always be careful to follow the direction of gas flow indicated by the arrow on the regulator.

Suitable tools must be used for the regulator fitting on the inlet and outlet hubs. Never effect leverage on the sleeve of the upper cover when fitting the regulator.

For all models with the filter inside, the regulator is best fitted at a suitable height from the ground so as to facilitate the filter cleaning (always fit a suitable gas filter upstream the regulator).

Make sure that the pipes are clean and aligned so the regulator is not under stress. Do not remove the perforated diaphragm breather cap and do not obstruct the hole, otherwise the regulator will not work.

Install the regulator so it does not touch plastered walls. Make sure that the regulator is suitable to the intended use.

MAINTENANCE

The regulator are completely maintenance-free. In the event of a breakdown, a general overhaul and factory testing is recommended.

To clean the filter simply remove the cover and replace the filter cartridge .

At every cleaning replace the gasket of the filter cover as well. After completing this operation check that there are no gas leaks through the cover itself.

IMPORTANT NOTICE:

ALL INSTALLATION AND MAINTENANCE OPERATIONS MUST BE CARRIED OUT SOLELY BY QUALIFIED PERSONNEL
