General data
In order to facilitate the use of limit switch valves in
applications where very low actuating forces and high
flowrates are required, Series 4 valves are equipped with
new mechanical devices designed for this purpose. The 4
Series includes one or two minivalves depending on the
function which the valve must perform.*
The mini valves reduce the actuation force required to
operate the main valve.
The functions available are as follows:
- 5-way/2-position (monostable) - spring-return
- 5-way/2-position (bistable) - double-pilot detented
*The mini-valves utilize a poppet valve to pilot-pressure
the main spool plunger.
