Asx 176 High Medium Gas Pressure Regulator

PRECAUTION FOR THE OPERATORS

Before proceeding with installation, commissioning or maintenance, operators must:

• Examine the safety provisions applicable to the installation in which they must work;
• Obtain the authorisations necessary to operate when required;
• Use the necessary personal protection devices(helmet, goggles, etc.);
• Ensure that the area in which they operate is equipped with the required collective protections and with necessary safety indications.

MAIN FEATURES

The ASX 176 is an axial flow pressure regulator suitable for use with previously filtered and non-aggressive gaseous fluids.

The ASX 176 is a “fail to close” piloted regulator and therefore it closes in the event of:

• - rupture of the main diaphragm;
• - rupture of the pilot diaphragm/s;
• - pilot circuit supply failure. The main specifications of this regulator are:
• - Design pressure: up to 102 bar;
• - Working temperature range: -20°C + 60 °C;
• - Ambient temperature: -20°C + 60 °C;
• - Inlet pressure range bpu: 0,8 to 100 bar;
• - Regulating range possible Wd: 0,3 ÷ 74 bar (depending on the model of pilot installed);
• - Minimum differential pressure 0.5 bar;
• - Precision class AC: up to 1 (depending on the operative conditions);
• - Closing pressure class SG: This value varies according to the operative conditions. Final user shall consider the real value of SG while choosing the setting pressure.
