The Sun Hydraulics HDDALCN297 (HDDALCN297) is a versatile solenoid-after check cartridge valve designed for lift-lower applications and is capable of being integrated directly into actuators. This hybrid valve combines a direct-acting solenoid poppet valve with a check function, allowing flow from the inlet port 2 to the system port 1. When the solenoid is de-energized, flow from port 2 to port 3 is blocked. The solenoid tube assembly is fatigue-rated for 5000 psi (350 bar) service, ensuring durability under high-pressure conditions. The manual override options include several configurations, such as D or L controls, which are intended for temporary actuation and have a mechanical life expectancy of approximately 7,000 cycles. This cartridge valve features a wet armature design where the working fluid surrounds the armature and can be affected by heat generated by the coil if energized for extended periods. It is suitable for load-holding applications and incorporates Sun's floating style construction to minimize internal part binding due to excessive installation torque or cavity-cartridge machining variations. The valve offers interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction, providing flexibility in installation. The HDDALCN297 has a capacity of 10 gpm (40 L/min), with a maximum operating pressure of 5000 psi (350 bar). It has a typical response time of 50 ms and maximum valve leakage at 110 SUS (24 cSt) of 10 drops/min at 5000 psi (0.7 cc/min at 350 bar). The check cracking pressure stands at 30 psi (2 bar), with a switching frequency capability of up to 15,000 cycles per hour. Additional features include compatibility with IP69K-rated coil connectors and weatherized coils for enhanced environmental protection.

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.
