The Sun Hydraulics HDDADCN712 (HDDADCN712) is a versatile solenoid-operated check cartridge, designed as a hybrid valve that integrates a direct-acting solenoid poppet valve after the check function. This robust component facilitates flow from inlet port 2 to system port 1, while blocking flow from port 2 to port 3 when the solenoid is de-energized. Predominantly used in lift-lower applications, it can be seamlessly incorporated into actuators for load holding purposes. The valve's solenoid tube assembly is engineered for high-pressure environments, rated for up to 5000 psi (350 bar). It features several manual override options, including configurations without manual override; however, these are not compatible with weatherized coils. The HDDADCN712 employs a wet armature design, which allows the working fluid to surround the armature and absorb heat generated by the coil. Users should consider this factor if the coil remains energized for extended durations, as certain fluids like water-glycol mixtures may degrade over time at elevated temperatures. Coils are interchangeable with other Sun Series 1 solenoid products and can be installed in either orientation on the tube. The valve also includes various coil connector options with ratings up to IP69K for enhanced environmental protection. Incorporating Sun's floating style construction minimizes internal part binding risks due to excessive installation torque or cavity/cartridge machining variations. With a capacity of 10 gpm (40 L/min) and a typical response time of 50 ms, this cartridge ensures efficient operation. It boasts a maximum valve leakage rate of 10 drops/min at 5000 psi (0.7 cc/min at 350 bar) and supports switching frequencies up to 15,000 cycles per hour. The manual override requires minimal force and offers a stroke length 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.
