The Twist/Lock manual override is a rotary, hand-actuated device originally for use on Sun's full flow solenoid and directional valves. The hand knob is constructed of a reinforced plastic for durability, heat resistance and stability in varying environmental conditions and is suitable for operation with a gloved hand. The override assembly incorporates a sealed-construction design thereby preventing the introduction of debris and other damaging contamination. Installed on a Sun solenoid valve, the override feature allows the operator to manually shift the de-energized valve. Sun has created a new family of manually operated valves by removing the core tube & coil and directly coupling the control. 2 position, 2 way, 3 way and 4 way valves, are now available. |
Sun's unique Twist and Lock Manual Controls are available in 3 configurations: |
|
 |
Detent/Lock Control 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. |
 |
Momentary Control 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. |
 |
Dual Operation Control 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 position by twisting counter-clockwise. |
The following table includes an overview of Sun's manually-operated valves along with links to additional detailed information. These valves are also listed with Sun's full line of Directional Cartridges.
