SOLENOID SAFETY GAS VALVES BLOCK UNIT

Solenoid safety gas valves block unit is a set of solenoid safety gas valves and other gas fittings unit assembled into a single gas train (gas filter, pressure regulator-stabilizer, motorized gas valve, safety relief gas valve, safety shut-off gas valve, pressure switch, etc.).

FIELD OF APPLICATION:

Solenoid safety gas valves block units are designed for monitoring and regulation of the gas environment (medium) supply in gas burners of hot water and steam boilers, melting and drying furnaces, gas heaters and other gas consuming devices.

DIAMETER NOMINAL:

• DN 15÷300.

HOUSING MATERIAL:

• steel: DN 15÷300;
• iron cast: DN-150, DN-200;
• aluminum: DN 15÷200.

COMBINED GAS VALVES BLOCK UNIT CAN BE EQUIPPED WITH ADDITIONAL DEVICES:

• read-off position indicators of the valve shutter, included in the block unit;
• pressure switches;
• leak-tightness control block unit (provides the monitoring of the valves leak-tightness included in the block unit before igniting the burner);
• different types of actuators.

VERSION:

• general industrial usage;
• explosion proof usage.

CLIMATIC VERSION:

• -30…+60 °С – installation in irregularly heated rooms;
• -45…+60 °С – installation under roof;
• -60…+60 °С – installation under roof;
• -60…+60 °С – outdoor installation.

AMBIENT OPERATING TEMPERATURE:

All solenoid safety gas valves block units manufactured by TERMOBREST are supplied in a version with ambient operating temperature from -60 up to +70 ° C.

Upon customer’s individual request, solenoid safety gas valves block units can be manufactured with ambient operating temperature from -45 up to +120 ° C.

Upon customer’s individual request, the valves block units with the read-off position indicators can be manufactured with ambient operating temperature from -45 up to +90 ° C (the upper range is limited by the permissible operating limit (range) of the read-off position indicator).

LEAK-TIGHTNESS CONTROL UNITS

Leak-tightness control unit is a device designed for automatic checking of the gas valves block units before ignition of the burner and ensures a safe start-up of the boiler.

It is used to control the leak-tightness of the gas train (gas valves block units) of industrial boiler burners and similar gas-burning devices.

HOUSING TYPE:

Figure 1 – housing version with IP41 protection degree for installation in a cabinet with mounting on a din-rail (СВР-1 series);

Figure 2 – version with IP54 protection degree with the possibility of outdoor installation under roof (СВР-2 series).

FUNCTIONALITY:

• Possibility of time setting for testing the valves in the process of monitoring the leak-tightness of the gas block unit;
• Interacts with various types of boiler control automation;
• Information about the leak-tightness of the solenoid valves is displayed on the LED panel;
• Provides control in manual or automatic modes;
• Can be completed with one or two pressure switches (mechanical or electronic types).
