The Sun Hydraulics HDDADCN912N (Material Number: HDDADCN912N) is a solenoid-after check cartridge valve designed for lift-lower applications and can be integrated directly into actuators. 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. Suitable for load holding applications, it features a wet armature design that exposes the working fluid to coil-generated heat, which could affect certain fluids over time. The solenoid tube assembly is rated for 5000 psi (350 bar) service, and its manual control assembly has a mechanical life expectancy of approximately 7,000 cycles. Manual override options are available but aren't compatible with weatherized coils. The valve uses Sun's floating style construction to reduce internal part binding due to installation torque or machining variations. It has a capacity of 10 gpm (40 L/min), with a response time of around 50 ms and maximum leakage at high pressure limited to 10 drops/minute (0.7 cc/min). The check cracking pressure is set at 30 psi (2 bar), and it supports switching frequencies up to 15,000 cycles per hour. The cartridge can be fitted with interchangeable coils from other Sun Series 1 solenoid products, offering connector options up to IP69K for enhanced environmental protection. Installation requires a torque of 30\u201335 lbf ft (41\u201347 Nm). Seal kits made from Viton are available for both the cartridge and coil components, ensuring reliable performance in demanding 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.
