The Sun Hydraulics DNCALXN71219 (DNCALXN71219) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve features a closed transition between positions, which minimizes 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, although reverse flow is possible but not recommended due to potential performance issues. The solenoid tube assembly is fatigue rated for service at pressures up to 5000 psi (350 bar), and it operates effectively without requiring minimum hydraulic pressure. Cartridges equipped with EPDM seals are compatible with phosphate ester fluids but should avoid contact with petroleum-based substances to prevent seal damage. The DNCALXN71219 employs a wet armature design, where the working fluid surrounds the armature and absorbs heat from the coil\u2014a consideration for long-term coil energization that could affect certain fluids like water-glycol mixtures. The valve offers various coil termination and voltage options, some with surge protection, ensuring flexibility in different applications. Its high-efficiency solenoid design provides substantial spool actuating force per watt, contributing to reliable valve operation. Coils are interchangeable within Sun Series 1 products and can be mounted in either direction on the tube. Additionally, this model includes Sun's floating style construction to reduce internal part binding from installation torque or machining variations. It fits into a T-31A cavity and has an operational capacity of 8 gpm (30 L/min) with a response time of approximately 50 ms. The maximum leakage rate at standard conditions is 10 in\u00b3/min (160 cc/min). For manual override operations, it requires a force of about 5 lbs at Port 1 and features a stroke length of .10 inches (2.5 mm).

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.
