This manually operated, 2-position, 2-way directional cartridge is a direct-acting, balanced spool valve used to
control the direction of flow in a hydraulic circuit. The valve is available in either a normally open or normally closed
configuration. Manual operation is achieved via Sun's Twist/Lock manual override mechanism and is designed for
intermittent (infrequent) use only.

TECHNICAL FEATURES
This valve is designed for intermittent use such as a manual override. The manual control assembly has a mechanical life expectancy of approximately 7,000
cycles.
The momentary/twist control option "T" allows the operator to momentarily shift the valve by twisting the knob clockwise and releasing. Once released, the valve
returns to its normal position.
The detent/lock control option "L" allows the operator to shift the valve into a mechanically detented position by twisting the knob counter-clockwise. This detented
position will be maintained until the operator twists the knob clockwise and allows the valve to return to its normal position. Please note that the detented position
is not intended for load holding applications but for temporary shifting only.
The dual-operation control option "D" allows the operator to either shift the valve momentarily by twisting the knob clockwise or shift it into a mechanically detented
postion by twisting counter-clockwise. Please note that the detented position is not intended for load holding applications but for temporary shifting only.
The control on this valve is meant to be operated by a person's hand. The control should not be modified, for instance fastening a lever to the knob. Under no
circumstances should the control be operated by other mechanical devices.
Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge
machining variations.
