#CMT# #/CMT# An air reservoir primary valve (36) is fitted in a central housing. It is connected via only a single control line (37) to separate start-up buttons (18). The arrangement forms a series of manual start-up stations. On operating a smoke extraction button (18), the control line (37) is vented. Such venting causes changeover in position of the reservoir primary valve (36), from its initial position into a starting position. #CMT#USE : #/CMT# A circuit supplying the pneumatic actuator cylinders of a smoke extraction plant. #CMT#ADVANTAGE : #/CMT# The pneumatic circuit supplies pneumatic actuator cylinders in a smoke extraction system (or in a smoke extraction and air ventilation system). It is constructed using compact components and is simple to install. Lightweight plastic tubing is suitable for the control- and other lines, enhancing installation flexibility. Each start button unit can be very compact. In addition to manually-operated buttons, electromagnetic or electrical operation is feasible. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# A schematic pneumatic circuit diagram of the arrangement is presented. 17 : reset button 18 : start-up buttons 31 : double-acting pneumatic cylinder 32 : connection point to compressor reservoir 36 : primary valve 37 : single control line. |
