The Sun Hydraulics DNCADSV648 (DNCADSV648) is a solenoid-operated, 4-way, 2-position cartridge valve that features a direct-acting, balanced spool with closed transition. This design characteristic minimizes the loss of oil during shifting, which is crucial in pilot control circuits. The valve operates with a capacity based on port 3 as the inlet and port 1 as the tank, although it allows for reverse flow; optimal performance in this mode is not assured. With a maximum operating pressure of 5000 psi (350 bar) and a response time of approximately 50 ms, the DNCADSV648 is designed for robust performance even under demanding conditions. This model incorporates an EPDM seal option suitable for systems using phosphate ester fluids while cautioning against exposure to petroleum-based substances that could damage the seals. The wet armature design of the valve ensures that the working fluid surrounds the armature which could lead to heat exposure if coils are energized over extended periods. This factor might affect performance with certain fluids like water-glycol mixtures that degrade at elevated temperatures. Sun Hydraulics has equipped this model with multiple coil termination and voltage options, enhancing its versatility and application across different systems. Additionally, coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The DNCADSV648 also benefits from Sun\u2019s floating style construction which reduces risks associated with internal parts binding due to installation issues or cavity/cartridge machining variations. This valve is particularly suited for applications requiring reliable and efficient directional control of hydraulic flow with minimal leakage and high switching frequency capabilities up to 15,000 cycles per hour. Its compact design (.60 lb or .30 kg) and robust construction make it an ideal choice for various hydraulic systems demanding high performance and reliability.

This solenoid-operated, 4-way, 2-position cartridge is a direct-acting, balanced spool directional valve. The transition between positions is closed. The closed transition greatly reduces the loss of oil when shifting which can be of particular importance in pilot control circuits.
- Valve capacity is based on port 3 as the inlet and port 1 as the tank. Although reverse flow is possible, the same performance cannot be guaranteed and is not recommended.
- The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- 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.
- A wide variety of coil termination and voltage options are available, with and without surge protection. See the CONFIGURATION section.
- The solenoid's unique magnetic design results in a high efficiency solenoid, yielding high spool actuating force per Watt expended, leading to reliable valve shifting.
- 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.
