Operation

Advantages

Disadvantages
 Normally closed with manual re-set GRC

  • Without power closes.

  • With power opens only by manual action.

  • Maximum safety for all uses.

  • At each failure of mains supply, valve closes.

  • When power returns valve has to be re-opened manually.

  • Not suitable for kitchens because, if no power, user tends to re-open valve with mechanical aids.

  • On return of power, safety system no longer functions.
