Technical specifications

The momentary/twist manual override is a rotary, hand-actuated device for use on Sun's full flow solenoid valves and certain Series P models. 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 "T" control in the cartridge model number. Sun kits for field conversion are also available. Please note that valves with the momentary/twist manual override are not suitable for load holding applications.

  • The momentary/twist override option "T" allows the operator to momentarily shift the valve by twisting the manual override clockwise and releasing. Once released, the valve returns to its de-energized position.
  • The manual control assembly has a mechanical life expectancy of approximately 7,000 cycles.
