The SV Series solenoid operated spool valve is made of anodized aluminum or stainless steel. The spool
valves have threaded port connections and/or Namur interface. In the below form, you can find the basic
pneumatic data for every member of the SV Series Spool valve.
The SV Series direct operated valves are suitable for single (mono-stable) solenoids with standard coils, and
various explosion-proof coils certified for use in hazardous areas (Zone 0, 1, 2 and Class I Div. 1&2 Groups
A, B, C and D)
SV Series Pilot operated spool valve is suitable for single/dual (mono/bi-stable) solenoid standard coils,
Cnomo interface coils or various explosion-proof coils certified for use in hazardous areas (Zone 0, 1, 2 and
Class I Div. 1&2 Group A, B, C and D)
As for S4/S4-2 Series Namur version , the 5/2 function spool valves are available to be mounted directly for
controlling double-acting actuators and the same spool valve also can be adapted by 3/2NC Namur function
interface plate for controlling single-acting actuators.
As for S4/S4-2 Series Namur version, the same spool valve can be adapted by 5/2 or 3/2 NC function Namur
interface plates for controlling double-acting or single-acting actuators.
