8.6 2-way ball valve with pneumatic quarter-turn actuator
The process valves VV1, VV2, and VV3 consist of a 2-way ball valve and are opened and closed by a
pneumatic quarter-turn actuator. The actuating device consists of a brass ball valve (1) with quarter-turn
actuator of type COPAR (4), rack and pinion principle with flanged-on 5/2-way NAMUR valve (3) with
solenoid coil (2) and position indicator (6). The outlet of the lower tanks into the mixing tank can be opened
by switching the 2W ball valves.
