The Sun Hydraulics DNCALCN71219 (DNCALCN71219) is a high-performance solenoid-operated, 4-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for closed transition between positions, significantly minimizing oil loss during shifting. This feature is particularly beneficial in pilot control circuits where maintaining hydraulic integrity is crucial. The DNCALCN71219 operates with a capacity of 8 gpm/30 L/min, utilizing port 3 as the inlet and port 1 as the tank. While reverse flow through the valve is possible, it is not recommended as performance consistency cannot be guaranteed. The solenoid tube assembly of this model is fatigue rated for robust operation at pressures up to 5000 psi (350 bar), and it does not require a minimum hydraulic pressure for operation, ensuring reliable functionality across various applications. Equipped with EPDM seals, the DNCALCN71219 is suited for use with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. The valve features a wet armature design where the working fluid surrounds the armature which may be exposed to heat if the coil remains energized over extended periods. This can lead to breakdowns in certain fluids like water-glycol mixtures. The DNCALCN71219 offers a variety of coil termination and voltage options, including models with surge protection. The coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Coil connector options are designed to meet ratings up to IP69K for enhanced durability and environmental protection. This model also incorporates Sun\u2019s floating style construction which helps minimize internal parts binding that could arise from excessive installation torque or variations in cavity/cartridge machining. With its robust design and versatile configurations, the DNCALCN71219 provides reliable performance and adaptability for diverse hydraulic system requirements.

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.
