The Sun Hydraulics HDDAMCV748 (HDDAMCV748) is a solenoid-operated check cartridge valve designed for lift-lower applications, integrating a direct-acting solenoid poppet valve after the check function. This hybrid valve allows 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. It features a fatigue-rated solenoid tube assembly suitable for service up to 5000 psi (350 bar), ensuring durability in demanding conditions. The valve is equipped with a manual override mechanism available in several configurations, including options without manual override, although these are not compatible with weatherized coils. The HDDAMCV748 utilizes a wet armature design, allowing the working fluid to cool the armature but requiring consideration of fluid type due to potential breakdown at high temperatures. The valve provides flexibility with interchangeable coils that can be mounted in either direction and offers coil connector options rated up to IP69K for enhanced environmental protection. It incorporates Sun's floating style construction, minimizing internal part binding due to installation torque or machining variations. This cartridge has a capacity of 10 gpm (40 L/min) and operates with a maximum leakage of 10 drops/min at 5000 psi (0.7 cc/min at 350 bar). Its check cracking pressure is set at 30 psi (2 bar), and it supports switching frequencies up to 15,000 cycles per hour. The manual override requires a force of approximately 5 lbs/1000 psi and has an override stroke of .10 inches (2.5 mm). With its robust design and reliable performance characteristics, this valve is suitable for load holding applications in various 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.
