The Sun Hydraulics DMDATRN948 (DMDATRN948) is a solenoid-operated, 3-way, 2-position cartridge valve that excels in applications requiring a direct-acting, balanced spool directional control. This model is particularly notable for its robust design, which includes a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar), making it suitable for high-pressure applications. The valve features closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, especially useful in pilot control setups where capacity is less critical. The DMDATRN948 operates without the need for a minimum hydraulic pressure, thereby facilitating its use in various fluid power systems. It includes options for manual override controls (D, L, and T), designed primarily for temporary actuation with a mechanical life expectancy of about 7,000 cycles. This model employs EPDM seals when configured for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. An additional advantage of this valve is its wet armature design which allows the working fluid to cool the armature\u2014necessary when the coil is energized for extended periods. Care should be taken with fluid selections as some may degrade under prolonged heat exposure. The DMDATRN948's versatility extends to its coil interchangeability with other Sun Series 1 solenoid products and incorporates Sun\u2019s floating style construction which minimizes internal parts binding due to installation stress or component variability. With a maximum flow capacity of 12 gpm (45 L/min) and quick response times typically around 50 ms, this valve supports efficient operations across various hydraulic systems. Its design also supports up to 15,000 switching cycles per hour, demonstrating both resilience and reliability in demanding operational conditions.
