The Sun Hydraulics HDDAMCV812N (HDDAMCV812N) is a versatile solenoid-after-check cartridge valve designed to integrate a direct-acting solenoid poppet valve with a check function. This hybrid valve is primarily used in lift-lower applications, providing reliable load holding capabilities by allowing flow from the inlet port 2 to system port 1 while blocking flow from port 2 to port 3 when the solenoid is de-energized. The valve's construction includes a fatigue-rated solenoid tube assembly for service up to 5000 psi (350 bar), making it suitable for demanding environments. It features a wet armature design, where the working fluid surrounds the armature, which can be beneficial for heat dissipation but may affect certain fluids like water-glycol mixtures over time. The HDDAMCV812N offers multiple manual override options, including configurations without manual override. However, note that manual override functionality is not compatible with weatherized coils. The valve's coil connector options provide protection ratings up to IP69K, ensuring robust performance in harsh conditions. The cartridge utilizes Sun\u2019s floating style construction to minimize internal binding and ensure consistent operation even under varying installation conditions. Key specifications include a capacity of 10 gpm (40 L/min), response time of approximately 50 ms, and maximum leakage of 10 drops/min at 110 SUS (24 cSt). It has a check cracking pressure of 30 psi (2 bar) and can handle switching frequencies up to 15,000 cycles per hour. The valve requires an installation torque between 30-35 lbf ft (41-47 Nm) and comes with Viton seal kits for both the cartridge and coil components. This combination of features makes the HDDAMCV812N an ideal choice for applications requiring precise control and reliability in 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.
