1 7.0/ RL 0 & 0: neumaic volume-flow conroller Used in conjuncion wih an orifice plae or a dnamic pressure sensor and a pneumaic damper drive for conrolling he air volume in air-condiioning ssems. For fixed, change-over or variable sepoins (A). Can also be used as a duc pressure conroller. All he A conrollers compl wih EN - and EN 7- (Ex G ) and can be emploed in Zone areas where here is a risk of explosion. Conforms o he regulaions on pressure equipmen (97//EG Ar..). Baseplae of hermoplasic; fron plae wih he adjusers for minimum and maximum limiaion of he sepoin signal; seings are made using a coin and he % scale. Conrol acion can be changed over. Suiable for mouning ono walls or rails (C-EN 500 and EN 500, accessor). Mus no be fied sanding on is end. Compressed-air connecion Rp 8 wih female hread.
