The Sun Hydraulics HDDATCV748 (HDDATCV748) is a solenoid-after check cartridge hybrid valve, combining a direct-acting solenoid poppet valve with a check function. This versatile valve facilitates 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. Ideal for lift-lower applications, it can be directly integrated into actuators and is suitable for load-holding tasks. The solenoid tube assembly is designed for high-pressure environments, fatigue-rated for 5000 psi (350 bar) service. The manual override options include D, L, and T controls with detent mechanisms meant for temporary actuation and offer a mechanical life expectancy of approximately 7,000 cycles. However, manual overrides are incompatible with weatherized coils. The HDDATCV748 features a wet armature design where the working fluid surrounds the armature, exposing it to coil-generated heat. This can affect fluids like water-glycol mixtures over time due to temperature-induced breakdowns that may form varnishes impacting cartridge function. Coils are interchangeable within Sun Series 1 solenoid products and can be mounted bidirectionally on the tube. Coil connector options provide ratings up to IP69K for enhanced environmental protection. This cartridge utilizes Sun's floating style construction to minimize binding risks from excessive installation torque or machining variations in cavity/cartridge interfaces. It fits into a T-11A cavity and has a capacity of up to 10 gpm (40 L/min). The maximum operating pressure is 5000 psi (350 bar), with a typical response time of 50 ms and minimal leakage at maximum conditions. The valve supports high switching frequencies up to 15,000 cycles per hour and requires specific manual override forces and strokes as detailed in its specifications.

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.
