Technical specifications
The dual manual override is a rotary, hand-actuated device for use on Sun's (full flow solenoid valves and FLeX series 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. Once installed on a Sun solenoid valve, the override feature allows the operator to manually shift the de-energized valve. Solenoid cartridges may be ordered in this configuration by specifying a "D" control in the cartridge model number. Sun kits for field conversion are also available. Please note that valves with the dual manual override are not suitable for load holding applications.
- The dual operation override option "D" allows the operator to either shift momentarily by turning clockwise or place it in the detent postion by turning counter-clockwise.
- The manual control assembly has a mechanical life expectancy of approximately 7,000 cycles.
- For proper operation of the twist-type manual overrides, it is important to grasp the cap fully before turning.
