The Sun Hydraulics HDDALCN924N (HDDALCN924N) is a solenoid-after check cartridge valve designed for lift-lower applications, where it can be integrated directly into the actuator. This hybrid valve combines a direct acting solenoid poppet valve with a check function, allowing 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. The fatigue-rated solenoid tube assembly supports service pressures up to 5000 psi (350 bar), making it suitable for load holding applications. Notably, this valve features a wet armature design, which means that the working fluid surrounds the armature and absorbs heat generated by the coil\u2014an important consideration if the coil remains energized for extended periods. The HDDALCN924N offers various manual override options and incorporates Sun's floating style construction to reduce internal part binding due to installation torque or machining variations. The valve is compatible with interchangeable coils from other Sun Series 1 solenoid products, which can be mounted in either direction. Coil connector options are available with ratings up to IP69K for enhanced environmental protection. Additionally, this cartridge has a mechanical life expectancy of approximately 7,000 cycles and supports switching frequencies of up to 15,000 cycles per hour. It fits within cavity T-11A and has a capacity of 10 gpm (40 L/min). The maximum valve leakage at 110 SUS (24 cSt) is minimal at just 10 drops/minute under maximum pressure conditions. With its robust construction and versatile functionality, this cartridge is an excellent choice for hydraulic systems requiring reliable directional control and pressure management in demanding environments.

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.
