The Sun Hydraulics HDDALCV72499 (HDDALCV72499) is a solenoid-after check cartridge hybrid valve that combines a direct-acting solenoid poppet valve with a check function. Designed for lift-lower applications, this valve can be integrated directly into an actuator. It features a check valve flow from inlet port 2 to system port 1, while flow from port 2 to port 3 is blocked when the solenoid is de-energized. The solenoid tube assembly is rated for fatigue service at pressures up to 5000 psi (350 bar). The manual override options include D, L, and T controls with a mechanical life expectancy of approximately 7,000 cycles. However, these overrides are not compatible with weatherized coils. This cartridge is suitable for load-holding applications and utilizes a wet armature design where the working fluid surrounds the armature, which can affect performance if the coil remains energized for extended periods. Interchangeable coils can be mounted in either direction and offer connector options rated up to IP69K for enhanced environmental protection. The valve incorporates Sun's floating style construction to minimize internal binding risks due to installation torque or machining variations. It fits into cavity T11A and belongs to Series 1 with a capacity of 10 gpm (40 L/min). Its maximum operating pressure is 5000 psi (350 bar), with typical response times of around 50 ms and minimal leakage rates at specified conditions. The check cracking pressure stands at 30 psi (2 bar), while its switching frequency can reach up to 15,000 cycles per hour. Manual override requires a force of approximately 5 lbs at Port 1 under certain conditions, with an override stroke of .10 inches (2.5 mm).

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.
