The Sun Hydraulics DNCAMJN298 (DNCAMJN298) is a solenoid-operated, 4-way, 2-position cartridge valve that features a direct-acting, balanced spool design for directional control. This valve is engineered with a closed transition between positions to significantly reduce oil loss during shifting, making it particularly beneficial for pilot control circuits. It is optimized for operation with port 3 as the inlet and port 1 as the tank; although reverse flow is possible, it is not recommended due to potential performance issues. The solenoid tube assembly of this valve is fatigue-rated for up to 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. Notably, the valve requires no minimum hydraulic pressure for operation due to its direct actuation mechanism. The DNCAMJN298 accommodates systems using phosphate ester fluids when configured with EPDM seals; however, these seals are susceptible to damage from petroleum-based fluids. It employs a wet armature design where working fluid envelops the armature, which may impact performance if the coil remains energized over extended periods\u2014particularly in systems using water-glycol mixtures that can degrade at high temperatures. This model offers various coil termination and voltage options, including surge protection features. Its high-efficiency solenoid design provides substantial spool actuating force per watt expended, contributing to reliable valve shifting. The coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. With coil connector options rated up to IP69K and additional weatherized kits available, this valve provides robust environmental protection. Constructed using Sun's floating style technique, this cartridge minimizes internal binding risks caused by excessive installation torque or cavity machining variations. It supports a capacity of 8 gpm (30 L/min) and allows manual override with specific force requirements and stroke measurements.

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.
