Beschreibung
Zusammenfassung:	The invention concerns a pneumatic control valve comprising a spring-returned control piston (1) whereto is attached a closure member (3) for the intake (4) and exhaust (5) paths provided in the actuator body (10). The invention is characterised in that said control piston (1) has an elliptic cross-section, its longitudinal axis being located in the same plane as the axis of the intake and discharge conduits (4', 5') of the fluid carried by the valve and the length of its minor axis being selected such that the length of the actuator body (10) does not exceed the space requirement of the connecting elements of the conduits to which said valve is connected.
