In order to facilitate the use of limit switch valves in applications where
very lowactuating forces and high flowrates are required, the Series 3
valves are equipped with new mechanical devices designed for this pur-
pose. The Series 3 valve is designed with a mechanical lever which when
operated releases an internal pilot signal to atmosphere. Actuation forces
are less than 50g (2N); (.5 lbf) and the sensitivity can be increased by
adding a “whisker” or rod of dia. 3mm to the lever (cross-thread of M5 x
.8 can be used to hold “whisker-rod” in place)
The functions available are as follows:
for the 3 Series:
- 3-way/2-position normally closed or normally open (spring return)
- 5-way/2-position (spring return)
* These valves have an internal mechanical spring return and a pilot-
pressure spool plunger that shifts upon actuation of the lever by depres-
surizing the spool plunger. Valve symbols shown are “at rest” next to the
actuator symbol.
