The Sun Hydraulics DMDAMBV297 (DMDAMBV297) is a high-performance solenoid-operated 3-way, 2-position cartridge valve engineered for precise hydraulic fluid direction control. This direct-acting, balanced spool directional valve features a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service, ensuring robust performance in demanding environments. The valve is designed with closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less crucial. The DMDAMBV297 operates without needing a minimum hydraulic pressure, enhancing its versatility across various hydraulic systems. It includes optional manual override controls (D, L, T), primarily intended for temporary actuation with a mechanical life expectancy of about 7,000 cycles. This model uses EPDM seals suitable for phosphate ester fluids but should avoid exposure to petroleum-based fluids which can degrade the seals. A distinctive feature of the DMDAMBV297 is its wet armature design; the working fluid envelops the armature which may be a consideration if the coil remains energized over extended periods as heat exposure can degrade certain fluids. The valve's coil components are interchangeable with other Sun Series 1 solenoid products and can be installed in either mounting direction. Additionally, it incorporates Sun\u2019s floating style construction to minimize internal part binding due to installation variances or machining discrepancies. Key specifications include a maximum flow capacity of 12 gpm (45 L/min), a typical response time of 50 ms, and a maximum operating pressure of 5000 psi (350 bar). The valve also supports up to 15,000 switching cycles per hour and requires a manual override force of about 5 lbs at 1000 psi for port activation. With these advanced features and specifications, the Sun Hydraulics DMDAMBV297 offers reliable performance and flexibility for specialized hydraulic applications.
