The Sun Hydraulics HDDALCN71299 (HDDALCN71299) is a solenoid-operated check cartridge valve that combines a direct-acting solenoid poppet valve with a check function, designed for versatile applications such as lift and lower operations. The valve allows flow from the inlet port 2 to system port 1, while blocking flow from port 2 to port 3 when the solenoid is de-energized. It features a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar) service, making it ideal for load-holding applications. The design includes multiple manual override options, though manual override functionality is not compatible with weatherized coils. This cartridge valve utilizes a wet armature design, where the working fluid surrounds the armature, potentially affecting performance if the coil is energized for extended periods. The valve supports interchangeable coils with other Sun Series 1 solenoid products and offers coil connector options rated up to IP69K for enhanced environmental protection. The HDDALCN71299 incorporates Sun's floating style construction to reduce internal part binding risks due to excessive installation torque or machining variations in cavity/cartridge setups. It fits into T11A cavities and belongs to Series 1 with a flow capacity of up to 10 gpm (40 L/min). The valve features a typical response time of 50 ms and exhibits minimal leakage at high pressures, ensuring efficient operation. It also has a check cracking pressure of 30 psi (2 bar) and supports high switching frequencies up to 15,000 cycles per hour. Installation requires specific torque settings between 30-35 lbf ft (41-47 Nm), and it comes with Viton seal kits for both cartridge and coil components, ensuring reliable sealing under various conditions.

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.
