Pneumatic control valve

The invention relates to a pneumatic control valve (1), such as a dual-circuit brake value transmitter in a compressed-air brake system of a vehicle for controlling a brake pressure corresponding to a desired braking effect. For an economical design that is easy to assemble, according to the invention the first plate valve (14) is arranged, in an axially movable and sealed manner, on a carrier (29), which can be inserted into the lower housing part (2) and which also comprises the accommodating space (42, 43) for the second valve piston (30), and the second plate valve (37) is arranged, in an axially movable and sealed manner, on a venting piece (46), which has a venting passage (47) led out from the lower housing part (2) and which can be inserted into the second accommodating space (50), which is accessible from the side facing the upper housing part (3). 本发明涉及种气动调节阀(1)，例如车辆压缩空气制动系统中的双回路制动值探测器，用于调整出相应于所希望的制动效果的制动压力。针对低成本且便于装配的设计规定，第板阀(14)能轴向移动地且密封地布置在能插装到壳体下部(2)中的支架(29)上，该支架也包括用于第二阀活塞(30)的容纳腔室(42、43)，并且第二板阀
