The Sun Hydraulics DNCAMLN828 (DNCAMLN828) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve features a closed transition between positions, significantly minimizing oil loss during shifting\u2014an important aspect for pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank; however, reverse flow is possible but not recommended due to potential performance inconsistencies. It boasts a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service and operates without needing a minimum hydraulic pressure. The DNCAMLN828 uses EPDM seals suitable for phosphate ester fluids, cautioning against exposure to petroleum-based substances which could damage the seals. Its wet armature design allows the working fluid to surround the armature, which can be affected by prolonged coil energization in certain fluids like water-glycol mixtures. The valve offers various coil termination and voltage options, including configurations with surge protection. The high-efficiency solenoid design ensures reliable valve shifting by providing substantial spool actuating force per watt expended. Coils are interchangeable within the Sun Series 1 solenoid products and can be mounted in either direction on the tube. With coil connector options rated up to IP69K, additional weatherized coils and kits enhance environmental protection. The Sun floating style construction minimizes internal part binding due to excessive installation torque or machining variations. Key specifications include a cavity size of T31A, series 1 capacity of 8 gpm (30 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, maximum leakage at specified conditions of 10 in\u00b3/min (160 cc/min), and a switching frequency of up to 15,000 cycles per hour. Manual override requires minimal force and stroke length for ease of operation.

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.
