The Sun Hydraulics HDDALCV297 (HDDALCV297) is a solenoid-after check cartridge that combines a direct-acting solenoid poppet valve with a check function, making it ideal for lift-lower applications. This hybrid 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. Designed for integration directly into actuators, it is suitable for load holding applications and features a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service. The valve offers several manual override options, although these are not compatible with weatherized coils. Utilizing a wet armature design, the working fluid surrounds the armature and absorbs heat generated by the coil, which could affect certain fluids if energized for extended periods. The interchangeable coils can be mounted in either direction and offer protection ratings up to IP69K depending on the connector options chosen. The HDDALCV297 incorporates Sun's floating style construction to minimize internal part binding due to installation torque or machining variations in cavity/cartridge configurations. It fits into T11A cavities and belongs to Series 1 with a capacity of 10 gpm (40 L/min). The response time is typically around 50 ms, with maximum leakage at specified conditions being minimal at 10 drops/min or approximately 0.7 cc/min at maximum pressure. Manual override requires an actuation force of about 5 lbs/1000 psi and has a stroke length of .10 inches (2.5 mm). With robust construction and versatile application potential, this cartridge valve is engineered for high performance and reliability in demanding hydraulic systems.

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.
