The Sun Hydraulics DNCALXN298 (DNCALXN298) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting applications with a balanced spool directional design. This valve is particularly suitable for pilot control circuits due to its closed transition feature, which minimizes oil loss during shifting. It operates with port 3 as the inlet and port 1 as the tank, although reverse flow is possible but not recommended for optimal performance. The solenoid tube assembly of this valve is fatigue rated for service up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. This valve does not require any minimum hydraulic pressure for operation and features a wet armature design, which allows the working fluid to surround the armature. This design can affect fluid integrity if the coil generates heat over prolonged periods, especially in water-glycol mixtures. The DNCALXN298 supports various coil termination and voltage options, with interchangeable coils compatible with other Sun Series 1 solenoid products, providing flexibility in configuration. The valve's magnetic design enhances efficiency by delivering high spool actuating force per watt expended, ensuring reliable shifting. It incorporates Sun's floating style construction to reduce internal binding risks due to installation torque or machining variations. This model has a capacity of 8 gpm (30 L/min) and offers a maximum operating pressure of 5000 psi (350 bar). It features a response time of approximately 50 ms and supports up to 15,000 cycles per hour switching frequency. Additional specifications include a manual override force requirement of 5 lbs/1000 psi (33 N/100 bar) at Port 1 and a manual override stroke of .10 inches (2.5 mm). The valve's hex size is .78 inches (22.2 mm), with an installation torque range between 30-35 lbf ft (41-47 Nm). The model weight is .60 lb (.30 kg). Seal kits are available in Viton material under part numbers 990431006 for cartridges and 990770006 for coils.

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.
