The Sun Hydraulics DNCATJN228 (DNCATJN228) is a solenoid-operated, 4-way, 2-position cartridge valve that features a direct-acting, balanced spool directional design. This valve is engineered with a closed transition between positions, significantly reducing oil loss during shifting\u2014an essential feature for pilot control circuits. It is designed to operate with port 3 as the inlet and port 1 as the tank, although reverse flow is possible but not recommended due to potential performance degradation. The solenoid tube assembly of the DNCATJN228 is fatigue-rated for service pressures up to 5000 psi (350 bar), ensuring durability and reliability in demanding applications. This valve requires no minimum hydraulic pressure for operation, making it versatile across various systems. The DNCATJN228 utilizes EPDM seals suitable for systems using phosphate ester fluids; however, these seals are incompatible with petroleum-based fluids. Its wet armature design allows the working fluid to surround the armature, which can be beneficial or detrimental depending on fluid type and coil energization duration\u2014fluids like water-glycol mixtures may degrade over time due to heat exposure. This model offers numerous coil termination and voltage options, including versions with surge protection. The high-efficiency solenoid design provides substantial spool actuating force per Watt expended, ensuring reliable shifting. Coils are interchangeable within the Sun Series 1 solenoid products line and can be mounted in either direction on the tube. The available coil connector options are rated up to IP69K for robust environmental protection. Incorporating Sun's floating style construction minimizes internal part binding risks from excessive installation torque or machining variations. The DNCATJN228 has a capacity of 8 gpm (30 L/min), supports a maximum operating pressure of 5000 psi (350 bar), and features a typical response time of 50 ms with leakage rates at maximum specified conditions kept minimal.

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.
