The Sun Hydraulics HDDALCV298 (Material Number: HDDALCV298) is a solenoid-after check cartridge designed for versatile hydraulic applications, particularly in lift-lower systems where direct integration into the actuator is beneficial. This hybrid valve combines a direct-acting solenoid poppet valve 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 features a fatigue-rated solenoid tube assembly capable of withstanding service pressures up to 5000 psi (350 bar), ensuring durability and reliability in demanding environments. The valve's design incorporates a wet armature, which allows the working fluid to surround the armature and be exposed to heat generated by the coil. This feature should be considered for applications involving long periods of coil energization, as certain fluids may degrade under these conditions. The HDDALCV298 offers multiple manual override options, though it's important to note that manual override functionality is not compatible with weatherized coils. This cartridge utilizes Sun's floating style construction to reduce internal part binding due to excessive torque or machining variations. It has a capacity of 10 gpm (40 L/min) and can handle high switching frequencies up to 15,000 cycles per hour. The valve's response time is typically around 50 milliseconds, with minimal leakage rates at maximum operating pressures. The check cracking pressure is set at 30 psi (2 bar), making it suitable for load-holding applications. For ease of maintenance and compatibility, coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Coil connector options provide protection ratings up to IP69K, ensuring robust performance even in harsh environmental conditions.

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.
