The Sun Hydraulics DMDADRV2E24V (DMDADRV2E24V) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve operates without the need for minimum hydraulic pressure, ensuring reliable function across a range of applications. The valve features a fatigue-rated solenoid tube assembly suitable for services up to 5000 psi (350 bar), making it robust for demanding environments. The DMDADRV2E24V incorporates closed transitions between spool positions B and R, optimizing performance by providing faster and more consistent response times particularly useful in pilot control applications where capacity is less critical. Additionally, the valve supports various manual override options including detent mechanisms (D or L control) intended for temporary actuation with a mechanical life expectancy of about 7,000 cycles. Designed with versatility in mind, the valve uses interchangeable coils compatible with other Sun Series 1 solenoid products and features a wet armature design that allows the working fluid to surround the armature. This design consideration is crucial when the coil remains energized over long periods as it can influence fluid integrity depending on the type used. It's important to note that cartridges configured with EPDM seals are specifically intended for systems using phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. Other technical specifications include a maximum flow capacity of 12 gpm (45 L/min), typical response times of 50 ms, and maximum leakage at 3000 psi not exceeding 5 in\u00b3/min. The valve also supports switching frequencies up to 15,000 cycles per hour and requires manual override force of approximately 5 lbs at 1000 psi for port activation. Installation specifications recommend torque settings between 30 -35 lbf\u00b7ft and highlight Sun's floating style construction which minimizes internal parts binding due to installation variances or machining discrepancies.
