The Sun Hydraulics DNCALJN71299 (DNCALJN71299) 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 features a closed transition between positions, which significantly reduces oil loss during shifting\u2014a critical feature for maintaining efficiency in pilot control circuits. The valve's configuration allows port 3 to serve as the inlet and port 1 as the tank outlet, though it does support reverse flow under certain conditions. Engineered for durability and performance, the DNCALJN71299 has a solenoid tube assembly that is fatigue rated for up to 5000 psi (350 bar), ensuring reliable operation under high-pressure conditions. It operates without the need for minimum hydraulic pressure, making it versatile across various applications. The wet armature design of the valve means that the working fluid surrounds the armature; this design consideration is important when dealing with long periods of coil energization which could affect fluid integrity over time due to heat exposure. Additionally, this model incorporates Sun Hydraulics' floating style construction which minimizes internal part binding caused by excessive installation torque or variations in cavity/cartridge machining. The DNCALJN71299 offers a variety of coil termination and voltage options including models with surge protection and environmental protection kits. Its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. This valve supports a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 8 gpm (30 L/min), with typical response times around 50 ms. It also features manual override capabilities and various seal options suitable for different fluids including phosphate ester fluids. The model\u2019s robust design and flexible configuration options make it an ideal choice for demanding hydraulic applications requiring reliable directional control and efficient operation.

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.
