The Sun Hydraulics DNCATCN628 (DNCATCN628) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. It features a closed transition between positions to minimize oil loss during shifting, which is crucial in pilot control circuits. The valve is optimized with port 3 as the inlet and port 1 as the tank, though reverse flow is possible; however, it may not guarantee the same performance and is not recommended. The solenoid tube assembly of this valve is fatigue rated for service pressures up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. This valve's direct actuation eliminates the need for minimum hydraulic pressure to operate, making it versatile in various applications. It supports systems utilizing phosphate ester fluids when configured with EPDM seals but should avoid exposure to petroleum-based fluids due to potential seal damage. The wet armature design allows the working fluid to surround and cool the armature; however, caution should be exercised with water-glycol mixtures that may degrade at elevated temperatures over time. The DNCATCN628 boasts a high-efficiency solenoid design that delivers substantial spool actuating force per watt expended, ensuring reliable operation. It offers various coil termination and voltage options with interchangeable coils compatible with other Sun Series 1 solenoid products. These coils can be mounted in either direction and provide environmental protection options up to IP69K ratings. The valve incorporates Sun's floating style construction to reduce internal part binding risks due to installation torque or machining variations. With a capacity of 8 gpm (30 L/min) and a typical response time of 50 ms, this model ensures efficient performance across numerous cycles per hour (up to 15,000). Its compact design features a manual override stroke of .10 inches (2.5 mm), requiring minimal force for operation adjustments.

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.
