2/2-way Servo-Assisted Solenoid Valve with Isolated Pilot

5282 G 1/2” - G 2”

• Unique isolated technology for
slightly contaminated fluids
• Independently adjustable
open / close rate
• Easily configurable for normally open
• Manual override 2 (A)

Completely unique servo-assisted solenoid valve with isolated pivoted Envelope Dimensions [mm] (see datasheet for details)
armature pilot. This valve design is much less sensitive to fluid contamina-
tion than plunger operated valves and therefore offers many advantages
in the process environment. The pilot section can be rotated in the field to
make the valve normally open.
