The Sun Hydraulics HDDALCV812 (HDDALCV812) is a solenoid-after check cartridge designed to function as a hybrid valve, incorporating a direct-acting solenoid poppet valve with a check function. This valve facilitates 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. It is particularly suitable for lift-lower applications and can be directly integrated into actuators. The solenoid tube assembly of this cartridge is fatigue rated for service up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. Equipped with various manual override options, including no manual override, the HDDALCV812 offers flexibility in operation. However, it is important to note that manual override functionality is not compatible with weatherized coils. The wet armature design allows working fluid to surround the armature, which can be affected by heat generated during prolonged coil energization. This characteristic requires consideration when using fluids like water-glycol mixtures that may degrade at elevated temperatures. The valve's construction incorporates Sun's floating style design, minimizing the risk of internal component binding due to excessive installation torque or cavity-cartridge machining variations. With a capacity of up to 10 gpm (40 L/min) and a response time of approximately 50 ms, this cartridge ensures efficient operation in load holding applications. Additionally, it features interchangeable coils with other Sun Series 1 solenoid products and offers coil connector options rated up to IP69K for enhanced environmental protection. The HDDALCV812 supports a maximum operating pressure of 5000 psi (350 bar) and provides reliable performance across various 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.
