While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Sun Hydraulics directly.***
The Sun Hydraulics HDDALCN (HDDALCN) is a solenoid-after check cartridge valve designed for hybrid applications, combining a direct-acting solenoid poppet valve with a check function. It facilitates 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. This valve is particularly suitable for lift-lower and load-holding applications and can be directly integrated into actuators. The solenoid tube assembly is rated for service up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. The valve offers several manual override options with a mechanical life expectancy of approximately 7,000 cycles, although these overrides are incompatible with weatherized coils. The HDDALCN utilizes a wet armature design where the working fluid surrounds the armature, which may affect fluid stability if the coil remains energized for extended periods. It supports interchangeable coils with other Sun Series 1 solenoid products and offers coil connector options rated up to IP69K for enhanced environmental protection. The valve incorporates Sun's floating style construction, minimizing potential binding of internal parts due to installation torque or machining variations. Additional specifications include a capacity of 10 gpm (40 L/min), response time of approximately 50 ms, and maximum leakage of 10 drops/min at 5000 psi (0.7 cc/min at 350 bar). The check cracking pressure is set at 30 psi (2 bar), and it supports a switching frequency of up to 15,000 cycles per hour. Installation requirements include a cavity size T-11A and an installation torque between 30 to 35 lbf ft (41 to 47 Nm). For maintenance, Viton seal kits are available for both cartridge and coil components.

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.
