The Sun Hydraulics HDDALCN248 (HDDALCN248) is a solenoid-after check cartridge hybrid valve designed for lift-lower applications, integrating a direct-acting solenoid poppet valve after the check function. The check valve allows flow from inlet port 2 to system port 1, while de-energizing the solenoid blocks flow from port 2 to port 3. This versatile valve can be directly integrated into actuators and is suitable for load-holding applications. It features a fatigue-rated solenoid tube assembly for service up to 5000 psi (350 bar). The manual override offers several options, including no override, with detent mechanisms in D or L controls intended for temporary actuation and boasting a mechanical life expectancy of around 7,000 cycles. Utilizing a wet armature design, the valve's working fluid surrounds the armature and absorbs heat generated by the coil, which can affect certain fluids like water-glycol mixtures over time. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted bidirectionally on the tube. Coil connector options provide ratings up to IP69K, with additional weatherized coils available for enhanced environmental protection. The HDDALCN248 incorporates Sun\u2019s floating style construction to minimize internal part binding due to excessive installation torque or machining variations. It fits into cavity T-11A in Series 1 configurations with a capacity of 10 gpm (40 L/min) and supports a switching frequency of up to 15,000 cycles per hour. The valve exhibits minimal leakage at maximum operating pressure and includes options for Viton seal kits. This product is ideal where precise control over hydraulic flow is essential 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.
