The Sun Hydraulics HDDALCN212N (HDDALCN212N) is a versatile solenoid-after check cartridge hybrid valve designed for lift-lower applications and direct integration into actuators. It combines a direct-acting solenoid poppet valve with a check valve, allowing 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. This valve is ideal for load holding applications and features a fatigue-rated solenoid tube assembly for service up to 5000 psi (350 bar). The manual override options include D, L, and T controls with a mechanical life expectancy of approximately 7,000 cycles, though it's important to note that manual override functionality isn't compatible with weatherized coils. This cartridge utilizes a wet armature design where the working fluid surrounds the armature, potentially affecting function if the coil is energized for extended periods. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction, offering connector options rated up to IP69K for enhanced environmental protection. The floating style construction minimizes internal binding risks due to excessive installation torque or machining variations. The HDDALCN212N fits into cavity T11A and supports capacities up to 10 gpm (40 L/min). It operates at a maximum pressure of 5000 psi (350 bar) with typical response times of around 50 ms. The valve's maximum leakage at viscosity levels of 110 SUS (24 cSt) is limited to 10 drops/minute at full pressure. It features a check cracking pressure of 30 psi (2 bar) and supports switching frequencies up to 15,000 cycles per hour. The manual override requires a force of approximately 5 lbs/1000 psi at Port 1 with an override stroke of .10 inches (2.5 mm).

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.
