The Sun Hydraulics HDDALCV299 (HDDALCV299) is a solenoid-after check cartridge valve that integrates a direct-acting solenoid poppet valve with a check function. Designed primarily for lift-lower applications, this hybrid valve allows 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. The solenoid tube assembly is fatigue-rated for up to 5000 psi (350 bar), making it suitable for high-pressure environments. The valve features various manual override options, including configurations without manual override, although it's important to note that manual overrides are not compatible with weatherized coils. This cartridge employs a wet armature design, allowing working fluid exposure to coil-generated heat, which can impact performance over time with certain fluids like water-glycol mixtures. It supports load-holding applications and boasts a mechanical life expectancy of approximately 7,000 cycles when equipped with D or L control detent mechanisms. The HDDALCV299 is compatible with Sun Series 1 solenoid products, featuring interchangeable coils that can be mounted in either direction and offering connector options rated up to IP69K for enhanced environmental protection. With a cavity size of T-11A and a capacity of 10 gpm (40 L/min), this cartridge ensures minimal leakage at maximum operating pressure conditions\u2014limited to 10 drops/min at 5000 psi (0.7 cc/min at 350 bar). Its robust construction incorporates Sun's floating style design, reducing the likelihood of internal binding due to installation torque or machining variations in cavities and cartridges. The valve's switching frequency reaches up to 15,000 cycles per hour, providing reliable performance in demanding applications.

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.
