The Sun Hydraulics DNCADTV71299 (DNCADTV71299) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve ensures efficient operation with its closed transition between positions, minimizing oil loss during shifting. This feature is particularly beneficial in pilot control circuits where maintaining hydraulic integrity is crucial. The valve operates with a capacity based on port 3 as the inlet and port 1 as the tank. While it allows for reverse flow, optimal performance in this mode is not assured and not recommended. The robust design includes a solenoid tube assembly that is fatigue rated for up to 5000 psi (350 bar), making it suitable for demanding applications. Additionally, the valve does not require a minimum hydraulic pressure to function, enhancing its versatility across various operating conditions. Equipped with EPDM seals, the DNCADTV71299 is specifically configured for use with phosphate ester fluids; however, exposure to petroleum-based substances should be avoided to prevent seal damage. It features a wet armature design where the working fluid surrounds the armature\u2014important to consider as prolonged coil energization could lead to fluid degradation at high temperatures. This model also offers flexibility in terms of coil terminations and voltage options, including variants with surge protection. The coils are interchangeable within Sun Series 1 solenoid products and can be mounted in either direction on the tube. Connection options provided can meet up to IP69K standards for environmental resilience. Furthermore, Sun Hydraulics incorporates their unique floating style construction into this model which helps prevent internal part binding due to installation variances or cavity/cartridge machining discrepancies. With a variety of configurations available and high-efficiency magnetic design ensuring reliable valve actuation, the DNCADTV71299 stands out as a dependable choice for specialized hydraulic applications requiring precise fluid control and durability.

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.
