  • (1) ­ Maximum working pressure

  • (2) ­ Flow of methane with pressure drop of 0.5 mbar (5mmWG) and 1 mbar (10 mmWG).

  • 100 mbar = 10 kPa = 1,000 mm.WG

Operation

Advantages

Disadvatages
 Normally closed GNC

  • Without power closes.

  • With power opens.

  • Ideal for boiler plants.

  • In event gas leak, detector switches off power to valve.

  • Power returns only with manual re-set of detector.

  • In event mains supply failure valve closes; when power returns valve re-opens automatically.

  • Not recommended for kitchens without thermo-couple.

  • In event failure of mains power, valve closes and flame goes out; when power returns valve re-opens and gas escapes causing a dangerous situation.
