The Sun Hydraulics HDDALCN724N (HDDALCN724N) is a solenoid-after check cartridge valve designed for hybrid applications, combining a direct-acting solenoid poppet valve with a check function. This versatile valve allows flow from the inlet port 2 to the system port 1, while blocking flow from port 2 to port 3 when the solenoid is de-energized. It is particularly suited for lift-lower and load-holding applications, and can be directly integrated into actuators. The valve features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), ensuring durability and reliability in demanding environments. The HDDALCN724N offers multiple manual override options, although these are not compatible with weatherized coils. The manual override mechanism has an estimated mechanical life of around 7,000 cycles and requires a force of 5 lbs/1000 psi at Port 1 for actuation. This cartridge employs a wet armature design, which exposes the working fluid to heat generated by the coil\u2014a consideration when using fluids like water-glycol mixtures that may degrade over time. Interchangeable coils with Sun Series 1 solenoid products allow flexibility in installation direction and offer connector options rated up to IP69K for enhanced environmental protection. The valve's floating-style construction minimizes internal binding risk due to installation torque or machining variations. With a capacity of 10 gpm (40 L/min), response time of approximately 50 ms, and check cracking pressure at 30 psi (2 bar), this cartridge provides efficient performance in various hydraulic systems. Additional specifications include a maximum leakage rate of 10 drops/min at 110 SUS (24 cSt) under full pressure conditions and compatibility with Viton seal kits for robust sealing performance.

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.
