The manually operated valves of Series 3 in 1/8”, 3/2 and 5/2 and of Series 4 in ¼”, 3/2, 5/2 and 5/3 were produced with different controls to meet a large number of needs. 3/2 distributors of Series 3 and 4 are of the Normally Closed type at rest when the pressure is on input 1 and, become of the Normally Open type at rest when the pressure is on the exhaust 3; the output being in 2 in both cases.
Strengths
5/2 distributors of Series 3 and 4 can be supplied by the exhausts 3 and 5 with two different pressures to, for example, supply a cylinder with an outlet pressure of the rod different from that of re-entry.
Series 1 was produced with two types of actuation: 3/2 with digital control and 3/2 and 5/2 with lever control.
