The Sun Hydraulics DMDAMAV297 (DMDAMAV297) is a solenoid-operated 3-way, 2-position cartridge valve that functions as a direct-acting, balanced spool directional valve. This model is designed for robust performance with a fatigue rating for 5000 psi (350 bar) service, making it suitable for high-pressure applications. The DMDAMAV297 features closed transitions between spools B and R, enhancing performance by providing faster and more consistent response times which are particularly beneficial in pilot control applications where capacity is less critical. This valve operates without the need for minimum hydraulic pressure, facilitating its use in a variety of fluid power systems. The manual override options available with this model include detent mechanisms intended for temporary actuation, with the mechanical life expectancy of these controls around 7,000 cycles. It is important to note that cartridges equipped with EPDM seals are specifically designed for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. Furthermore, the DMDAMAV297 utilizes a wet armature design which helps in heat management around the coil but requires consideration of fluid type as certain fluids may degrade under prolonged exposure to heat. The interchangeable coils compatible with other Sun Series 1 solenoid products add versatility to this model. Additionally, its construction incorporates Sun's floating style design which minimizes internal part binding due to installation variances or machining discrepancies. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and typical response times of 50 ms. The valve also supports switching frequencies up to 15,000 cycles per hour and features manual override requirements that ensure operational control under varying pressures. This compact unit weighs just 0.60 lb (0.30 kg) and has been engineered to meet rigorous industrial demands while maintaining precise control and reliability in hydraulic systems.
