<p>The pneumatic brake control valve is particularly for printing paper, where the chamber-type brake body has a slide surface with suction holes and is connected to an exhauster. It is double valve (STe with two valve units, the first one (VI) connecting the body (BK) to the exhauster (UT) and the second (V2) the former to the ambient air. It can have flow passages with rotary throttle flaps (DK1, DK2) offset for 90 deg. from each other on a common shaft (GW), so as to shut off one or the other. Their dia. can be that of the passages (DF1, DF2), no additional seal being necessary. A rotary magnet (DM) can be mounted on the shaft.</p> |
