The Sun Hydraulics HDDADCN72499 (HDDADCN72499) is a solenoid-after check cartridge hybrid valve designed for lift-lower applications, integrating seamlessly into actuators. This valve features a direct acting solenoid poppet valve positioned after the check function, allowing flow from inlet port 2 to system port 1 while blocking flow from port 2 to port 3 when the solenoid is de-energized. It is engineered for high-pressure environments with a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar). The valve's design includes several manual override options, although these are not compatible with weatherized coils. The wet armature design exposes the working fluid to coil-generated heat, which can affect certain fluids over time. The HDDADCN72499 employs Sun's floating style construction to minimize internal binding due to excessive torque or machining variations. It offers a capacity of 10 gpm (40 L/min) and features interchangeable coils with other Sun Series 1 products. Additional coil connector options provide ratings up to IP69K for enhanced environmental protection. Key specifications include a response time of approximately 50 ms, maximum leakage of 10 drops/min at 110 SUS (24 cSt), and a manual override force requirement of 5 lbs/1000 psi at Port 1. The valve's hex size is .78 inches (22.2 mm), and it requires an installation torque between 30 and 35 lbf ft (41 and 47 Nm). Seal kits are available in Viton material for both the 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.
