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, safety relief gas valve, safety shut-off gas valve, pressure switch, etc.) and motorized gas valve
Motorized gas valve included in the unit controls the gas supply to the gas burner and regulates the gas flow rate.
Upon customer's request, the valve block can be manufactured complete with additional automation devices (pressure switches, position indicators of valves), as well as in general industrial and waterproof versions.
The gas block can be designed according to the scheme, which provides the possibility to check the tightness of the valves included in the block before ignition of the burner.

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:
