The Sun Hydraulics DNCALAN71219 (DNCALAN71219) is a high-performance solenoid-operated, 4-way, 2-position cartridge valve designed for efficient control in hydraulic systems. This direct-acting, balanced spool directional valve features a closed transition between positions, minimizing oil loss during shifting. This characteristic is especially beneficial in pilot control circuits where maintaining fluid integrity is crucial. With a capacity of 8 gpm/30 L/min based on port 3 as the inlet and port 1 as the tank, the DNCALAN71219 ensures reliable operation even under reverse flow conditions, although optimal performance in reverse is not guaranteed. The valve operates without requiring a minimum hydraulic pressure and includes EPDM seals suitable for phosphate ester fluids; however, these seals are susceptible to damage from exposure to petroleum-based substances. This model incorporates a wet armature design where the working fluid surrounds the armature. While this design aids in cooling, prolonged energization can lead to fluid degradation at high temperatures. The valve's solenoid tube assembly is fatigue rated for up to 5000 psi (350 bar), ensuring durability and long service life under demanding conditions. The DNCALAN71219 offers various coil termination and voltage options, including configurations with surge protection. Its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The solenoid\u2019s unique magnetic design enhances efficiency by maximizing spool actuating force per watt expended. Additional features include an IP69K rating for certain coil connector options, enhancing resistance to environmental factors. The valve also utilizes Sun\u2019s floating style construction which reduces the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With its robust design and versatile configuration options, the DNCALAN71219 provides reliable performance and adaptability for various hydraulic applications.
