The Sun Hydraulics HDDAMCV298 (HDDAMCV298) is a versatile solenoid-after check cartridge valve, designed to integrate seamlessly into lift-lower applications. This hybrid valve combines a direct-acting solenoid poppet valve with a check function, facilitating flow from inlet port 2 to system port 1 while blocking flow from port 2 to port 3 when the solenoid is de-energized. Engineered for durability, the solenoid tube assembly is fatigue-rated for service up to 5000 psi (350 bar). The cartridge offers several manual override options, including configurations without manual override, although these are not compatible with weatherized coils. Notably suitable for load-holding tasks, this valve features a wet armature design that allows fluid exposure to coil-generated heat\u2014important when considering long-duration energizing and potential fluid degradation. The HDDAMCV298 model incorporates Sun's floating style construction to mitigate internal part binding due to installation torque or machining variations. It boasts a capacity of 10 gpm (40 L/min) and maintains maximum operating pressure at 5000 psi (350 bar). With a typical response time of 50 ms and minimal leakage at high viscosity levels, the valve ensures efficient operation. Its check cracking pressure stands at 30 psi (2 bar), and it supports switching frequency up to 15,000 cycles per hour. For manual operation, it requires an override force of approximately 5 lbs/1000 psi at Port 1 and provides an override stroke of .10 in. (2.5 mm). The solenoid tube diameter measures .75 in. (19 mm), with a hex size of .78 in. (22.2 mm) and installation torque ranging from 30-35 lbf ft (41-47 Nm). Additionally, Viton seal kits are available for both cartridge and coil components, ensuring robust sealing solutions for varied 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.
