The Sun Hydraulics DMDATPN224 (DMDATPN224) is a high-performance solenoid-operated 3-way, 2-position cartridge valve, designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve ensures reliable control and operation in various configurations. The model is particularly noted for its fatigue-rated solenoid tube assembly which can handle services up to 5000 psi (350 bar), making it suitable for high-pressure environments. The DMDATPN224 features closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times especially in pilot control applications where capacity is less critical. It operates without requiring a minimum hydraulic pressure, adding to its versatility in different system conditions. The manual override options available with the D or L control are designed for temporary actuation, with a mechanical life expectancy of around 7,000 cycles. Configured with EPDM seals, the valve is intended for use with phosphate ester fluids; however, it is sensitive to exposure to petroleum-based fluids which can damage the seals. Its wet armature design allows the working fluid to surround the armature, which could be a consideration if the coil remains energized over extended periods as it may affect certain types of hydraulic fluids. This model also boasts interchangeable coils with other Sun Series 1 solenoid products and incorporates Sun's floating style construction to minimize internal parts binding due to installation torque or cavity/cartridge machining variations. With a maximum operating capacity of 12 gpm (45 L/min) and quick response times typically around 50 ms, the DMDATPN224 offers an efficient solution for directing flow in hydraulic systems while maintaining strict leakage controls at high pressures.
