The Sun Hydraulics DNCADCV648 (DNCADCV648) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise control in hydraulic systems. Featuring a direct-acting, balanced spool with a closed transition between positions, this valve minimizes oil loss during shifting which is crucial in maintaining the efficiency in pilot control circuits. It is engineered for robust performance with a valve capacity designated with port 3 as the inlet and port 1 as the tank, and it is capable of handling reverse flow albeit with altered performance. This model boasts a fatigue rating for the solenoid tube assembly at 5000 psi (350 bar), ensuring durability under high-pressure conditions. It operates effectively without any minimum hydraulic pressure requirement and incorporates EPDM seals specifically for use with phosphate ester fluids, avoiding damage from petroleum-based substances. The DNCADCV648 utilizes a wet armature design where the working fluid surrounds the armature; this design consideration is vital when the coil remains energized over extended periods. Additionally, it offers flexibility in terms of coil termination and voltage options\u2014including models with surge protection\u2014and maintains compatibility across various environmental conditions, supported by weatherized coils and kits for enhanced protection. The valve's magnetic design enhances efficiency by maximizing spool actuating force per watt expended, ensuring reliable operation. Its construction incorporates Sun\u2019s floating style to reduce risks of internal parts binding due to installation or machining discrepancies. With an array of technical specifications like a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 8 gpm (30 L/min), and swift response times typically around 50 ms, the DNCADCV648 stands out as a versatile solution suitable for demanding applications requiring precise hydraulic control 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.
