The Sun Hydraulics HDDADCV212N (HDDADCV212N) is a solenoid-after check cartridge hybrid valve designed for efficient fluid control in hydraulic systems, particularly in lift-lower applications. This valve combines a direct-acting solenoid poppet with a check valve function, allowing flow from inlet port 2 to system port 1 while blocking flow from port 2 to port 3 when the solenoid is deenergized. It features a robust solenoid tube assembly fatigue-rated for up to 5000 psi (350 bar) service, making it suitable for load holding applications. The manual override options include various configurations, though they are not compatible with weatherized coils. The wet armature design ensures that working fluid surrounds the armature, which can be crucial when the coil is energized for extended periods as some fluids may degrade over time due to heat exposure. Coils are interchangeable with other Sun Series 1 solenoids and can be mounted in either direction, with connector options rated up to IP69K for enhanced environmental protection. This valve uses Sun's floating style construction to prevent internal binding due to installation torque or machining variations. It fits into a T-11A cavity and has a capacity of 10 gpm (40 L/min), with a typical response time of 50 ms and maximum leakage of 10 drops/min at 5000 psi (0.7 cc/min at 350 bar). The check cracking pressure is set at 30 psi (2 bar), and it supports switching frequencies up to 15,000 cycles per hour. Installation requires a torque of between 30 - 35 lbf ft (41 - 47 Nm), and the valve includes Viton seal kits for both cartridge and coil components.

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.
