The Sun Hydraulics HDDALCN72419 (HDDALCN72419) is a solenoid-after-check cartridge hybrid valve that combines a direct-acting solenoid poppet valve with a check function. This versatile valve allows check valve 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 is designed for lift-lower applications and can be integrated directly into an actuator, making it suitable for load-holding tasks. The solenoid tube assembly is fatigue-rated for service up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. The valve features several manual override options, including configurations without manual override, though these are not compatible with weatherized coils. The HDDALCN72419 utilizes a wet armature design, where the working fluid surrounds the armature and absorbs heat from the coil, which can impact performance if energized for extended periods\u2014particularly with water-glycol mixtures that may form varnishes over time. Coils are interchangeable with other Sun Series 1 solenoids and can be mounted in either direction, providing flexibility in installation. Coil connectors offer ratings up to IP69K for enhanced environmental protection. Constructed with Sun's floating style design, this cartridge minimizes internal part binding due to excessive torque or machining variations. It operates within a cavity T-11A with a capacity of 10 gpm (40 L/min) and offers a response time of approximately 50 ms. The valve's maximum leakage at 110 SUS (24 cSt) is limited to 10 drops/min at 5000 psi (0.7 cc/min at 350 bar). Additional specifications include a check cracking pressure of 30 psi (2 bar) and a switching frequency of up to 15,000 cycles per hour.

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.
