2.1 Application
Gas pressure regulator (GDR), indirect-acting (operating with auxiliary power), for systems acc. to
DVGW work sheets G 491 (A) and G 600 (A) (TRGI).
Can be used as an equipment component on gas consumption facilities as defined in EC Directive EU/2016/426
Can be used for the gases defined in DVGW work sheet G 260 / G 262 and neutral non-aggressive gases.
(other gases on request)
