Mechanically Operated Valves Series 1 And 3

The 3/2-way monostable valves of series 3 are normally closed in the rest position when pressure is supplied in 1 and are normally open when pressure is supplied on connection 3, the user port 2 remaining unchanged. The 5/2-way valves of Series 3 may be supplied via the ports 3 and 5 with two different pressures if a cylinder has to be operated using a delivery pressure which is different from the return pressure.
