Spool type, two or three position direct operated valves with
threaded solenoids.
Solenoids are made by:
• wet type screwed tube, different for AC and DC power supply, with
integrated
manual override pin
• interchangeable coils, specific for AC or DC power supply, easily
replaceable
without tools - see section 5 for available voltages
Standard coils protection IP65.
Optional coils are available with IP67 AMP Junior Timer, Deutsch,
lead wire
connections (options XJ, XK, XS) or with North American Standard
Certification
CURUS, without connector (option XUL).
Wide range of interchangeable spools , see section 2.
The valve body is 3 chamber type made by shell-moulding casting
with wide
internal passages ensuring low pressure drops
