The Sun Hydraulics DNCAMAN298 (DNCAMAN298) 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, making it ideal for pilot control circuits. The valve's capacity is optimized 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 is fatigue-rated for service up to 5000 psi (350 bar), and the valve operates without requiring minimum hydraulic pressure. Configured with EPDM seals, this valve is suitable for systems using phosphate ester fluids but should avoid petroleum-based fluids to prevent seal damage. The valve incorporates a wet armature design where the working fluid surrounds the armature, potentially impacting performance if the coil remains energized for extended periods. High temperatures can cause certain fluids like water-glycol mixtures to degrade over time. A variety of coil termination and voltage options are available, some featuring surge protection. The solenoid's magnetic design ensures efficient operation with high spool actuating force per watt expended. Coils are interchangeable within Sun Series 1 products and can be mounted in either direction. The DNCAMAN298 utilizes Sun's floating-style construction to reduce internal binding risks due to installation torque or machining variations. It fits into cavity T-31A and has a capacity of 8 gpm (30 L/min). With a typical response time of 50 ms and maximum leakage at 10 in\u00b3/min (3000 psi), this valve supports switching frequencies up to 15,000 cycles per hour. The manual override requires a force of approximately 5 lbs at Port 1 with a stroke of .10 inches. Additional weatherized coils and kits offer enhanced environmental protection, while coil connector options provide ratings up to IP69K for robust field applications.

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.
