The Sun Hydraulics DMDALRN814N (DMDALRN814N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust and efficient hydraulic control. This direct-acting, balanced spool directional valve features a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service, ensuring durability and reliability in demanding applications. The valve\u2019s design incorporates closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, especially beneficial in pilot control setups where capacity is less critical. The DMDALRN814N operates without requiring a minimum hydraulic pressure, facilitating its use in various fluid power systems. It is equipped with manual override options (D or L control), which include a detent mechanism intended for temporary actuation, supporting a mechanical life expectancy of around 7,000 cycles. For environments using phosphate ester fluids, cartridges with EPDM seals are recommended; however, these should not be exposed to petroleum-based fluids as it could compromise the seal integrity. This model also employs a wet armature design allowing the working fluid to surround the armature which helps manage heat during prolonged coil energization \u2014 an important consideration for maintaining fluid integrity over time. Furthermore, the interchangeable coils compatible with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement procedures. Additional features include Sun\u2019s floating style construction that minimizes internal parts binding due to installation torque or machining variations of cavity/cartridge. The DMDALRN814N has a flow capacity of 12 gpm (45 L/min) and can handle maximum operating pressures up to 5000 psi (350 bar). Its response time is typically around 50 ms, and it supports a switching frequency of up to 15,000 cycles per hour. This valve's compact design includes manual override functionalities requiring minimal force and stroke, making it user-friendly while ensuring precise control in hydraulic systems.
