The Sun Hydraulics DNCADWV72499 (DNCADWV72499) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic fluid control in various applications. This direct-acting, balanced spool directional valve ensures a closed transition between positions, significantly minimizing oil loss during shifts\u2014a crucial feature for maintaining efficiency in pilot control circuits. With a capacity based on port 3 as the inlet and port 1 as the tank, the DNCADWV72499 allows for reverse flow, although it does not guarantee the same performance and advises against this mode for optimal operation. The solenoid tube assembly of this valve is fatigue rated for service up to 5000 psi (350 bar), making it robust for high-pressure applications. Notably, this valve operates without requiring a minimum hydraulic pressure, enhancing its versatility across various hydraulic systems. Designed with EPDM seals, this cartridge is specifically configured for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. The wet armature design of the DNCADWV72499 means that the working fluid surrounds the armature which can be exposed to heat if the coil remains energized over extended periods. This design consideration is vital when using fluids like water-glycol mixtures that may degrade under prolonged heat exposure. Additionally, Sun Hydraulics offers a variety of coil termination and voltage options for this model, including versions with surge protection. The magnetic design of the solenoid contributes to high efficiency and reliable valve shifting by maximizing spool actuating force per watt expended. The coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. For further customization and environmental protection against harsh conditions, various weatherized coils and kits are available. The DNCADWV72499 also incorporates Sun\u2019s floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations.

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.
