The Sun Hydraulics DMDATNN71299 (DMDATNN71299) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. It features a direct-acting, balanced spool with manual override options, including D, L, and T controls that provide temporary actuation with a mechanical life expectancy of about 7,000 cycles. This valve is optimally used in applications requiring robust performance as it can handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). The DMDATNN71299 is designed with a fatigue-rated solenoid tube assembly for continuous service and durability. Its unique construction incorporates Sun's floating style to minimize internal parts binding due to excessive installation torque or cavity/cartridge machining variations. The valve also features interchangeable coils with other Sun Series 1 solenoid products for enhanced versatility and maintenance ease. This model utilizes EPDM seals suitable for systems using phosphate ester fluids while avoiding exposure to petroleum-based fluids which can damage the seals. The wet armature design surrounds the armature with the working fluid, which helps in heat management but requires consideration of fluid properties under prolonged energization. With its fast response time typically around 50 ms and the ability to switch up to 15,000 cycles per hour, the DMDATNN71299 is an excellent choice for systems where rapid directional changes are critical. This valve ensures minimal leakage at high pressures and provides consistent performance even under challenging operational conditions.
