The Sun Hydraulics HDDALCV72419 (HDDALCV72419) is a solenoid-operated check cartridge valve designed for lift-lower applications, integrating a direct-acting solenoid poppet valve with a 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 is suitable for load-holding applications and can be directly integrated into an actuator, making it versatile for various hydraulic systems. The solenoid tube assembly is fatigue-rated for service up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. The valve features a wet armature design, which allows the working fluid to surround the armature, exposing it to heat generated by the coil; this should be considered if the coil remains energized for extended periods. The cartridge offers multiple manual override options, although these are not compatible with weatherized coils. Its manual control assembly has an approximate mechanical life expectancy of 7,000 cycles. The Sun floating style construction minimizes internal parts binding due to excessive installation torque or machining variations. With a capacity of 10 gpm (40 L/min) and a maximum operating pressure of 5000 psi (350 bar), this valve provides reliable performance in demanding environments. Additional specifications include a response time of approximately 50 ms and a switching frequency of up to 15,000 cycles per hour. The coil connectors offer ratings up to IP69K, providing options for enhanced environmental protection. This model's versatility and robust construction make it an ideal choice for applications requiring precise control and reliable load holding 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.
