The Sun Hydraulics DNCATAN628 (DNCATAN628) is a solenoid-operated, 4-way, 2-position cartridge directional valve featuring a direct-acting, balanced spool design. This valve is engineered with a closed transition between positions, significantly minimizing oil loss during shifting\u2014a crucial advantage in pilot control circuits. It operates optimally with port 3 as the inlet and port 1 as the tank, though reverse flow is possible but not recommended due to potential performance inconsistencies. The solenoid tube assembly is fatigue-rated for up to 5000 psi (350 bar), ensuring durability in demanding applications. The valve does not require any minimum hydraulic pressure for operation and incorporates EPDM seals for compatibility with phosphate ester fluids while being unsuitable for petroleum-based substances. The DNCATAN628 utilizes a wet armature design, where the working fluid surrounds the armature and absorbs heat from the coil. This feature necessitates caution if the coil remains energized over extended periods, particularly with water-glycol mixtures that may degrade and form varnishes affecting functionality. The solenoid's magnetic design maximizes efficiency by delivering high spool actuating force per watt expended, ensuring reliable valve shifting. Coils are interchangeable within Sun Series 1 solenoid products and can be mounted in either direction on the tube. This model offers various coil termination and voltage options, some with surge protection capabilities. Coil connectors are rated up to IP69K for enhanced environmental protection, with additional weatherized coils available. The valve incorporates Sun's floating style construction to prevent internal binding due to installation torque or machining variations in cavity-cartridge setups. With a capacity of 8 gpm (30 L/min) and a response time of approximately 50 ms, this robust valve supports high-frequency switching up to 15,000 cycles per hour while maintaining minimal leakage at specified conditions.

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.
