Manual Overrides
English Chinese (Simplified)

comatrol hydraulic cartridge valves

"Comatrol solenoid valves, where noted in the individual catalog pages, have optional"

"manual overrides.  The manual overrides are “safety” features for when power is lost and the solenoid needs to be operated.  2 position valves with manual overrides, when activated, shift the valve to its energized position.  Some 3 position valves come standard with a one-direction, push-pin manual override. When the manual override is pushed, the spool shifts following the logic of energizing S2.  Manual override options are intended for emergency use only and are not intended for continuous operation."
