The Sun Hydraulics DNCATAV71299 (DNCATAV71299) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct operation with balanced spool directional control. It features a closed transition between positions, which significantly reduces oil loss during shifting\u2014a critical advantage in pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank; however, reverse flow is possible but not recommended due to performance limitations. The solenoid tube assembly is fatigue-rated for service at pressures up to 5000 psi (350 bar), ensuring reliability under demanding conditions. This valve does not require minimum hydraulic pressure for operation and incorporates EPDM seals suitable for systems using phosphate ester fluids, though exposure to petroleum-based fluids can damage these seals. The DNCATAV71299 employs a wet armature design where the working fluid surrounds the armature, potentially affecting function if exposed to prolonged coil heat. A variety of coil termination and voltage options are available, including those with surge protection. The valve's high-efficiency solenoid delivers robust spool actuating force per watt, promoting dependable shifting operations. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Connector options provide ratings up to IP69K for enhanced environmental protection. This model uses Sun's floating style construction to mitigate internal part binding due to excessive installation torque or machining variations. It fits into cavity T31A, has a series rating of 1 with an 8 gpm (30 L/min) capacity, and operates at a maximum pressure of 5000 psi (350 bar). The typical response time is approximately 50 ms, with maximum leakage at specified conditions being minimal. Manual override requires minimal force and stroke distance, ensuring ease of use in manual operations.

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.
