The Sun Hydraulics DMDAMBV628 (DMDAMBV628) is a solenoid-operated 3-way, 2-position cartridge valve that functions as a direct-acting, balanced spool directional valve. This robust component is designed for high-performance applications with its fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar). The valve features closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, particularly suitable for pilot controls where capacity is less critical. This direct-actuated valve operates without requiring a minimum hydraulic pressure, adding to its versatility in various system configurations. It includes options for manual override through D, L, or T control types, with a mechanical life expectancy of about 7,000 cycles. The manual override is specifically designed for temporary actuation. Additionally, the DMDAMBV628 can be fitted with EPDM seals suitable for systems using phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it could damage the seals. The valve's wet armature design allows the working fluid to surround the armature which helps in heat management but could affect fluid integrity over prolonged periods of energization. It supports a maximum flow capacity of 12 gpm (45 L/min) and offers quick response times typically around 50 ms. The interchangeable coils are compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Moreover, the construction incorporates Sun\u2019s floating style to minimize internal part binding due to installation torque or machining variations. This precision-engineered valve ensures reliable operation under demanding conditions while maintaining minimal leakage and high switching frequency capabilities.
