The Sun Hydraulics DNCAMCN748 (DNCAMCN748) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. Known for its closed transition between positions, this valve significantly minimizes oil loss during shifting, making it highly suitable for pilot control circuits. It is designed with port 3 as the inlet and port 1 as the tank; while reverse flow is possible, it is not recommended due to potential performance inconsistencies. The solenoid tube assembly is rated for fatigue at a maximum operating pressure of 5000 psi (350 bar), ensuring robust performance under demanding conditions. This valve operates without requiring any minimum hydraulic pressure and utilizes EPDM seals specifically for systems using phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. The DNCAMCN748 incorporates a wet armature design where the working fluid surrounds the armature and absorbs heat from the coil. Extended energization of the coil may affect certain fluids like water-glycol mixtures due to potential breakdown at high temperatures. The solenoid\u2019s magnetic design achieves high efficiency with significant spool actuating force per watt expended, ensuring reliable operation. It offers various coil termination and voltage options, including surge protection capabilities, with interchangeable coils compatible with other Sun Series 1 products. The valve features a cavity T-31A in Series 1 with an 8 gpm (30 L/min) capacity and exhibits a typical response time of 50 ms. Its maximum leakage rate at 110 SUS (24 cSt) is limited to 10 in\u00b3/min (160 cc/min). With a switching frequency of up to 15,000 cycles per hour, it supports high-frequency operations effectively. Its construction minimizes internal binding risks due to excessive installation torque or machining variations. The valve's installation requires a torque range between 30-35 lbf ft (41-47 Nm), and it comes equipped with Viton seal kits for both cartridge and coil 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.
