Valve arrangement for gaseous and liquid media, e.g. for piston/cylinder unit, has at least two 2/2-way valves arranged in row and digitally-pneumatically coupled to form multi-way valve assembly which is controlled by electric unit

摘要

The valve arrangement (5) comprises at least two, but preferably four, 2/2-way valves (1,2,3,4) which is controlled by an electric unit (6) via at least one bus terminal (8) and at least one sensor terminal (9,10). The valves act as fast switching plate anchor valves switching at the speeds lower than 5 milliseconds. Each valve includes a valve chest (16), valve seat (18), plate anchor (21), electric coil (22) and a yoke of magnet (23). The coil (22) is controlled by the electric unit (6).
