The Sun Hydraulics DNCAMTN228 (DNCAMTN228) 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, minimizing oil loss during shifting, which is particularly beneficial in pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank; reverse flow is possible but not recommended due to potential performance issues. Engineered to endure high pressures, its solenoid tube assembly is fatigue-rated for up to 5000 psi (350 bar). The valve operates without requiring a minimum hydraulic pressure and incorporates EPDM seals suitable for phosphate ester fluid systems; however, these seals are incompatible with petroleum-based fluids. Utilizing a wet armature design, the valve allows working fluid exposure to coil-generated heat, which can affect certain fluids like water-glycol mixtures over time. The DNCAMTN228 offers versatility with various coil termination and voltage options, including surge protection. Its high-efficiency solenoid delivers substantial spool actuating force per watt, ensuring reliable operation. Coils are interchangeable within Sun Series 1 products and offer mounting flexibility. Connector options provide protection ratings up to IP69K for enhanced environmental resilience. The valve incorporates Sun's floating style construction to reduce internal part binding risks due to installation torque or machining variations. With a cavity size of T31A and series designation of 1, the valve boasts an 8 gpm (30 L/min) capacity and a response time of approximately 50 ms. It handles maximum operating pressures of up to 5000 psi (350 bar) with minimal leakage at specified conditions. Capable of switching frequencies up to 15,000 cycles per hour, it requires manual override forces of approximately 5 lbs/1000 psi at Port 1 with an override stroke of .10 inches (2.5 mm). The valve's compact design includes a solenoid tube diameter of .75 inches (19 mm), hex size of .78 inches (22.2 mm), and installation torque range of 30-35 lbf ft (41-47 Nm).

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.
