The mechanically operated valves in the Series 3 (1/8”) have been designed
with three different types of actuation:
– plunger
– lever/roller
– unidirectional lever/roller
In each case, return is effected by a mechanical spring.
The Series 3, 3-way/2-position valves are normally closed in the rest position
when the pressure is supplied at P and are normally open when the pressure is
supplied at the connection R, the user port A remaining unchanged.
Moreover, the 5-way/2-position valves may be supplied via the ports R and S
with two different pressures if a cylinder has to be operated using a delivery
pressure which is different from the return pressure. They can be operated
with vacuum down to -.9 bar (28” Hg). Additionally, the series 3 valves can
be supplied with 2 different pressures into ports 3 and 5 if a cylinder requires
different extend and retract forces. The series 1 valves offer a more rugged,
compact design with steel operator interfaces.
