PRESSURE REGULATORS Process Management

A/100 Regulators A/100 Series Pressure Regulator The regulators of the A/100 series due to their operating specifications are mainly used in those system where sudden capacity variations are required, or else, where the cut-off of the gas distribution is controlled by solenoid valve, such as for the feeding of burners. They can be used with natural gas, manufactured gas, air, propane and other gases, as long as they do not contain a high percentage of benzole. The A/100 series regulators are spring controlled single seated, whit not counterbalanced valve disc. They are usually supplied with safety...

A/100 Regulators Regulator Operation The movements of the diaphragm (D) are transmitted to the valve disc (O) by the stem (S) and the lever (L). The downstream pressure through the pulse pipe (I) exerts a force under diaphragm (D) and this force is counteracted by the adjusting spring (M). The gas pressure on the diaphragm tends to close the valve disc; the antagonist action of the adjustment spring tends to open it. Under normal conditions the balance between these antagonist actions positions the valve disc in such a way as to ensure a constant pressure and therefore the downstream capacity....

A/100 Regulators Shut-off Device Operation The A/100 series pressure regulators can be fitted with an OS/66 slam-shut valve. This safety device operates independently of the regulator and, according to customer request, can be made to trigger by any pressure variation, whether above or below set point, or by both. Outlet pressure acting upon diaphragm (D) is counteracted by maximum pressure spring (M2), thus overcoming the action of the minimum pressure valve (M3). Under such conditions, the moving part (E) of the valve is held in balance so that lever (L) is aligned with the projecting part...

A/100 Regulators Slam-Shut Device The following slam-shut devices are used with A/100 series regulators with built-in shut-off device: • OS/66 Spring loaded Technical Features Servomotor Body Resistance (bar) Body Aluminium Cover Steel Diaphragm NBR Rubber Carbon dioxide Following flow tables (referred to Natural Gas) are advised for an optimal use of the A/100 series regulators. For other gases with different densities, the flow rate must be multiplied by the correction factor: Outlet Pressure mbar Seat Diameter
