The Sun Hydraulics HDDADCN299 (HDDADCN299) is a versatile solenoid-after check cartridge valve designed for use in lift-lower applications and can be directly integrated into actuators. This hybrid valve combines a direct-acting solenoid poppet valve with a check function, 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. It is fatigue-rated for service up to 5000 psi (350 bar), making it suitable for load-holding applications. The valve features a wet armature design, which means the working fluid surrounds the armature and can be affected by heat generated by the coil during prolonged energization. This could impact fluids like water-glycol mixtures over time due to potential varnish formation. The HDDADCN299 offers several manual override options, including models with no manual override, although it's important to note that manual override functionality is incompatible with weatherized coils. The D, L, and T manual control assemblies have an approximate mechanical life expectancy of 7,000 cycles and are intended for temporary actuation. The valve's construction incorporates Sun's floating style design to minimize internal part binding due to excessive installation torque or cavity machining variations. With a capacity of 10 gpm (40 L/min) and a typical response time of 50 ms, this cartridge provides efficient operation. It features interchangeable coils compatible with other Sun Series 1 solenoid products, allowing installation flexibility. Coil connector options offer protection ratings up to IP69K, and additional weatherized coils are available for enhanced environmental protection. The HDDADCN299 also includes a T11A cavity configuration and requires specific installation torque settings between 30 - 35 lbf ft (41 - 47 Nm).

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.
