10. Manufacturer's declaration.

Pipe line connection types:
- Coupling type for DN 15 - 50 mm;
- Flange type for DN 25 - 100 mm.

• By default the valves are manufactured with connection flanges PN6.
  Valves in nominal diameters DN 32...200 can be manufactured with connection flanges PN16.

• Operating environment temperature: –60...+70 °C.
  A version with a medium temperature of -45...+120 °C is available as a special order.
  Valves with position indicators are optionally available with a working medium temperature of -45...+90 °C (upper limit is limited by the permissible operating limit of the position indicator).

• In a standard way, the solenoid gas valves with 220 V AC power source of solenoids are produced in an energy-saving version. The gas valve includes a control board that provides a reduction in consumed power up to 50% of the initial in 10 seconds after switching on.

Three-position solenoid safety gas valve is a device designed for remote control of flow of non-aggressive gaseous mediums in three different modes:

• maximum flow rate mode;
• average (intermediate) flow rate mode;
• off mode.
