The Sun Hydraulics DMDATRN814N (DMDATRN814N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. It features a direct-acting, balanced spool design which ensures reliable operation without the need for minimum hydraulic pressure. The valve is particularly noted for its closed transition between positions B and R, enhancing performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less critical. This model boasts a robust construction with a fatigue rating of 5000 psi (350 bar), making it suitable for demanding environments. The manual override option includes a detent mechanism designed primarily for temporary actuation, with an expected mechanical life of approximately 7,000 cycles. Notably, the valve uses EPDM seals configured specifically for systems utilizing phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based substances. Additional features include interchangeable coils compatible with other Sun Series 1 solenoid products and a wet armature design where the working fluid surrounds the armature. This design consideration is crucial as prolonged coil energization can lead to fluid degradation in certain conditions. The valve also incorporates Sun\u2019s floating style construction which minimizes internal part binding due to installation torque or machining variations of cavity/cartridge. With specifications like a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and rapid response times typically around 50 ms, the DMDATRN814N is engineered for efficiency and reliability in hydraulic systems operations. Its compact form factor (.60 lb/0.30 kg) and ease of installation with standard manual override features make it an adaptable solution for various hydraulic control applications.
