SV08-24 Valve

SYMBOL:SV08-22 Valve symbol

DESCRIPTION
A solenoid-operated, two-way, normally closed, direct-acting, spool-type, screw-in cartridge
valve, designed to operate as a bidirectional blocking solenoid valve. It can be used as a switching
valve for variable flow pump controls. A stainless steel version could be specified for SCR/EGR emission
and exhaust control systems.

OPERATION
When de-energized, the SV08-24 blocks flow in both directions.
When energized the spool shifts to allow flow in both directions.
Operation of Manual Override Option: To override, push button in and twist
counterclockwise 180°. The internal spring will push the button out. In this position
the valve may be only partially shifted. To assure full override shift, pull the button
out to its fullest extension and hold it in this position. To return to normal operation,
push button in, twist clockwise 180°, and release. Override will be detented in this position.
