The Sun Hydraulics DMDATPV648 (DMDATPV648) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for hydraulic applications requiring reliable directional control. This direct-acting, balanced spool valve features a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar), making it suitable for rigorous industrial applications. The valve's design ensures closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times ideal for pilot control operations where capacity is less critical. The DMDATPV648 operates without the need for minimum hydraulic pressure, facilitating its use in various fluid power systems. It includes manual override options with a detent mechanism designed for temporary actuation, supporting mechanical life expectancy around 7,000 cycles. Special attention is given to the valve's compatibility with fluids; models with EPDM seals are specifically intended for systems using phosphate ester fluids, while exposure to petroleum-based substances should be avoided to prevent seal damage. This model also incorporates a wet armature design where the working fluid surrounds the armature. Such a configuration can influence fluid integrity under prolonged energization, potentially affecting performance in specific applications like those involving water-glycol mixtures. Additionally, it features interchangeable coils compatible with other Sun Series 1 solenoid products and adopts Sun\u2019s floating style construction to minimize internal parts binding due to installation or machining variances. Key specifications include a flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and a maximum operating pressure of 5000 psi (350 bar). The valve also supports a switching frequency of up to 15,000 cycles/hr and requires manual override force of about 5 lbs at 1000 psi for Port 1. Its robust yet compact design ensures reliability and ease of integration into existing hydraulic systems.
