The Sun Hydraulics DNCADTV528 (DNCADTV528) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic control in various applications. This direct-acting, balanced spool directional valve features a closed transition between positions, minimizing oil loss during shifting which is crucial in maintaining the efficiency of pilot control circuits. It operates with a capacity of 8 gpm/30 L/min and can handle a maximum operating pressure of 5000 psi/350 bar. The valve is notable for its ability to function without minimum hydraulic pressure, enhancing its versatility across different hydraulic systems. The DNCADTV528 is built with EPDM seals suitable for systems using phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. Its wet armature design ensures that the working fluid surrounds the armature which could be a consideration if the coil remains energized for extended periods since some fluids may degrade under prolonged heat exposure. Additionally, this model offers an array of coil termination and voltage options and includes surge protection options as well. With a robust construction that incorporates Sun's floating style design, the DNCADTV528 minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. It also boasts quick response times typically around 50 ms and supports up to 15,000 switching cycles per hour. The manual override feature requires minimal force and has a stroke length adequate for effective manual operation adjustments. Overall, the Sun Hydraulics DNCADTV528 valve is engineered for reliability and optimal performance in demanding hydraulic applications where precise fluid control and durability are essential.

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.
