The Sun Hydraulics DMDATRN528 (DMDATRN528) is a solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This valve is specifically crafted for high-performance applications with its fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar). The design includes closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. The DMDATRN528 operates without the need for a minimum hydraulic pressure, enhancing its versatility in various system configurations. It includes options for manual override through D, L, or T control types, with a mechanical life expectancy of approximately 7,000 cycles. For systems utilizing phosphate ester fluids, cartridges equipped with EPDM seals are available; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. This model also incorporates a wet armature design allowing the working fluid to surround the armature which helps manage the heat generated by the coil. This feature requires consideration of fluid type as some may degrade under prolonged exposure to heat. Interchangeability of coils with other Sun Series 1 solenoid products adds to the flexibility and ease of use of this valve. Furthermore, Sun Hydraulics has engineered this valve with a floating style construction to minimize internal binding due to installation variances or excessive torque. The DMDATRN528 supports up to 12 gpm (45 L/min) flow capacity and offers rapid response times typically around 50 ms. Its robust construction and thoughtful design make it an excellent choice for demanding directional control applications in hydraulic systems.
