ABSTRACT:
Stage for a system for distributing pneumatic control signals by electrical means, comprising a large number of associated stages. Each stage comprises a removable electrical valve (141) having an electro-magnet (33) of very low power, and a fixed socket (5) into which it fits: a pneumatic amplifier (57) is housed in the body (51), of the socket and feeds relatively large amounts of fluid to an outlet connector (26) when it is activated by the outlet of a low flow pneumatic switch (40); a non-return valve (88) protects the amplifier against pressure perturbations in the discharge duct (4). Numerous thin stages of a thickness close to 17.5 mm. can with advantage be used as an interface between a pneumatic installation (28) and a control center (24) supplying low level electrical signals.
