The Sun Hydraulics HDDADCN (HDDADCN) is a solenoid-after check cartridge hybrid valve, integrating a direct acting solenoid poppet valve with a check function. The design facilitates 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. This configuration is ideal for lift-lower applications and can be directly integrated into actuators, making it suitable for load holding tasks. The valve operates with a maximum pressure of 5000 psi (350 bar) and has a capacity of 10 gpm (40 L/min). Its solenoid tube assembly is fatigue-rated for high-pressure service, ensuring durability in demanding environments. The HDDADCN model offers several manual override options, though it's important to note that weatherized coils are not compatible with manual overrides. The override mechanism is designed for temporary actuation and has an estimated mechanical life expectancy of around 7,000 cycles. This valve employs a wet armature design, where the working fluid surrounds the armature and interacts with heat generated by the coil. Users should be mindful of fluid types, as certain mixtures like water-glycol can degrade over time under these conditions. Interchangeable coils with IP69K rating options provide flexibility in various environments and are compatible across Sun Series 1 products. The cartridge's floating style construction minimizes internal binding risks due to installation torque or machining variations. Additional features include a typical response time of 50 ms and minimal leakage rates at high viscosity levels. For installation, it requires a torque specification between 30 to 35 lbf ft (41 to 47 Nm), with seal kits available for maintenance needs.

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.
