The Sun Hydraulics HDDADCN628 (HDDADCN628) is a solenoid-after check cartridge hybrid valve designed for applications requiring precise control, such as lift-lower operations. This valve integrates a direct-acting solenoid poppet valve with a check function, allowing flow from the inlet port 2 to system port 1 while blocking flow to port 3 when the solenoid is de-energized. It is particularly suitable for load-holding applications and can be directly incorporated into an actuator. The cartridge features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. This model offers various manual override options, although it should be noted that these are not compatible with weatherized coils. The manual override mechanism has an estimated mechanical life of about 7,000 cycles and requires a force of 5 lbs at 1000 psi for operation. The wet armature design exposes the armature to working fluid, which can affect performance if the coil is energized for extended periods\u2014especially with fluids like water-glycol mixtures. The HDDADCN628 supports interchangeable coils with other Sun Series 1 solenoid products and provides coil connector options rated up to IP69K for enhanced environmental protection. It incorporates Sun's floating style construction to minimize internal binding due to installation torque or machining variations. Additional specifications include a capacity of 10 gpm (40 L/min), typical response time of 50 ms, and maximum valve leakage at specified conditions of 10 drops/minute at 5000 psi (0.7 cc/min at 350 bar). This robust design makes it highly effective in demanding hydraulic systems requiring reliable performance and precise control.

This solenoid-after check cartridge is a hybrid valve incorporating a direct acting solenoid poppet valve teed in after the check function. The check valve flow is from the inlet (port 2) to the system (port 1). With the solenoid de-energized flow from (port 2) to (port 3) is blocked. This combination valve is typically used in lift/lower applications and can be integrated directly into the actuator.
- The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
- On models equipped with the D or L control, the detent mechanism in the manual override is meant for temporary actuation. The D, L and T manual control assembly has a mechanical life expectancy of approximately 7,000 cycles.
- This cartridge has several manual override choices, including no manual override. See the CONFIGURATION section. Please note: Manual override functionality is not compatible with weatherized coils.
- Suitable for load holding applications.
- This valve utilizes a wet armature design. This means that the working fluid surrounds the armature and is exposed to the heat generated by the coil. This can be a factor if the coil is energized for long periods of time. Some fluids, notably water/glycol mixtures, break down at these temperatures over time and form varnishes that will affect the function of the cartridge.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- Coil connector options offer ratings up to IP69K. See individual coil product pages for details. Additional weatherized coils and kits are available for more complete environmental protection.
- 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.
