The Sun Hydraulics DNCADCN628 (DNCADCN628) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve features a closed transition between positions, minimizing oil loss during shifting which is crucial in maintaining the efficiency of pilot control circuits. The valve's configuration allows for port 3 to be used as the inlet and port 1 as the tank, though it supports reverse flow under certain conditions. Engineered for robust performance, the DNCADCN628 can handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 8 gpm (30 L/min). Its quick response time of approximately 50 ms ensures timely operation critical in various applications. The solenoid tube assembly is fatigue rated for high-pressure service, enhancing the valve's durability and reliability over extensive use. This model incorporates Sun Hydraulics' unique floating style construction which reduces risks associated with internal parts binding due to installation torque or cavity/cartridge machining variations. Additionally, it employs a wet armature design where the working fluid surrounds the armature; this design consideration is vital when the coil is energized for extended periods as it affects fluid integrity and performance. The DNCADCN628 offers flexibility with numerous coil termination and voltage options, including models with surge protection. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. For environments requiring additional protection against elements, weatherized coils and kits are available. This versatile valve is an ideal choice for applications requiring reliable switching performance and minimal hydraulic pressure loss while providing options to suit various operational environments and system fluids.

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.
