The Sun Hydraulics DMDATPV248 (DMDATPV248) is a solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This model is specifically engineered for high-performance applications with its fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar) service. The valve's spools B and R maintain a closed state during transitions between positions, enhancing performance by ensuring faster and more consistent response times, particularly when used as pilot controls. The DMDATPV248 operates without requiring a minimum hydraulic pressure, making it versatile for various applications. It includes manual override options with the D or L control featuring a detent mechanism designed for temporary actuation and an expected mechanical life of approximately 7,000 cycles. For systems utilizing phosphate ester fluids, cartridges with EPDM seals are recommended to prevent damage from petroleum-based substances. This model employs a wet armature design where the working fluid surrounds the armature. This setup is crucial for understanding the operational environment since prolonged energization can lead to fluid breakdown in certain conditions. The interchangeable coils with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement. Additionally, the valve incorporates Sun\u2019s floating style construction to minimize internal parts binding caused by installation torque or machining variations of the cavity/cartridge. Key specifications include a flow capacity of up to 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), quick response time typically around 50 ms, and very minimal maximum valve leakage at high pressures. The manual override requires a force of about 5 lbs at 1000 psi per port, indicating ease of operation under pressure settings. With its robust construction and versatile design features, the DMDATPV248 is well-suited for demanding directional control applications requiring precise fluid handling and reliability.
