The Sun Hydraulics DNCADWV528 (DNCADWV528) is a solenoid-operated, 4-way, 2-position cartridge valve that stands out for its direct-acting, balanced spool directional control capabilities. This model is specifically engineered to ensure a closed transition between positions, significantly minimizing oil loss during shifts which is crucial in maintaining the efficiency of pilot control circuits. The DNCADWV528 allows for a valve capacity with port 3 as the inlet and port 1 as the tank outlet, although it does support reverse flow under certain conditions. With a robust design, the solenoid tube assembly of this valve is fatigue rated for up to 5000 psi (350 bar), ensuring reliable operation under high-pressure scenarios. It operates without requiring a minimum hydraulic pressure, adding to its versatility across various applications. The DNCADWV528 features EPDM seals configured for compatibility with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based substances. This model incorporates a wet armature design where the working fluid surrounds the armature. This setup needs consideration as prolonged energization of the coil can lead to fluid degradation at high temperatures. Sun Hydraulics has equipped the DNCADWV528 with various coil termination and voltage options, enhancing its adaptability and performance across different operational environments. Additional features include interchangeable coils with other Sun Series 1 solenoid products and multiple coil connector options that offer up to IP69K protection ratings. The construction employs Sun's floating style which minimizes internal parts binding\u2014a common issue due to excessive installation torque or machining variations in cavity/cartridge setups. Overall, the DNCADWV528 is designed for reliability and efficient performance in controlling directional flow within hydraulic systems, making it a suitable choice for applications requiring precise fluid control under varying pressures and conditions.

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.
