The Sun Hydraulics HDDALCV828 (HDDALCV828) is a versatile solenoid-after-check cartridge valve, designed for lift-lower applications and suitable for integration directly into actuators. This hybrid valve features a direct-acting solenoid poppet valve that is combined with a 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 fatigue-rated for service up to 5000 psi (350 bar) and incorporates Sun's floating style construction to reduce the risk of internal parts binding due to installation torque or machining variations. The valve supports a capacity of up to 10 gpm (40 L/min) and exhibits a typical response time of 50 ms. With a maximum leakage rate of 10 drops/min at 5000 psi, it ensures efficient operation in load-holding scenarios. The HDDALCV828 offers multiple manual override options, including configurations without manual override, although these are not compatible with weatherized coils. The manual control assembly boasts approximately 7,000 cycles of mechanical life expectancy. The wet armature design allows working fluid exposure to coil heat, which should be considered if the coil remains energized for extended periods; fluids like water-glycol mixtures may degrade under such conditions. Coil connectors provide protection ratings up to IP69K, enhancing environmental resilience. This cartridge's compact specifications include a T11A cavity, Series 1 compatibility, and interchangeable coils with other Sun Series 1 solenoid products. It requires an installation torque between 30-35 lbf ft (41-47 Nm) and features a check cracking pressure of 30 psi (2 bar). Additionally, the valve allows switching frequencies up to 15,000 cycles per hour and necessitates a manual override force of approximately 5 lbs/1000 psi at Port 1.

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.
