Abstract:
An electromagnetically actuatable pneumatic directional control valve (10; 10) comprising a compressed air network connection (11), a vent (12) and at least one working connection (13) for a compressed air consuming unit, a valve member (20) that is actuated by an electromagnet (21) and, for an alternating closure of a working conduit (17) that leads to a working connection (13) in relation to the compressed air network connection (11) and the vent (12), is alternatingly placed against one of two valve seats (18, 19) of which the one valve seat is embodied at the conduit mouth of a supply conduit (15) that leads to the compressed air network connection (11) and another valve seat is embodied at the conduit mouth of a ventilation conduit (16) that leads to the vent (12), the electromagnet (21), the valve member (20), the working conduit (17), the supply conduit (15), and the ventilation conduit (16), along with corresponding valve seats (18, 19) and the vent (12) are combined in a valve housing (24) and the connections (11, 13) for the compressed air network and the compressed air consuming units are disposed in a connecting plate (25; 25) that can be separated from the valve housing (24) and is detachably connected to the valve housing (24), that the compressed air network connection (11) has a connection fitting (34) that is accessible on one plate side (251) of the connecting plate (25; 25), and has a connecting bore (35) that is let into the remote plate side (252) of the connecting plate (25; 25), which fitting and bore communicate with each other and are adapted to each other so that the connection fitting (34) can be plugged into the connecting bore (35) of a second directional control valve (10; 10) in an airtight manner with the interposition of a radially sealing O-ring (37), and that connecting means are disposed on each of the plate sides (251, 252) of the connecting plate (25; 25) that carry the connection fitting (34) or the connecting bore (35), which connecting means are embodied so that the connecting means correspond to each other to produce a connection between the two connecting plates (25, 25) of the two directional control valves (10, 10), with the connection fitting (34) and the connecting bore (35) plugged into each other.
