The Sun Hydraulics DMDAMAN628 (DMDAMAN628) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve ensures reliable operation with no minimum hydraulic pressure required for functionality. It features a robust design with a fatigue rating of 5000 psi (350 bar), making it suitable for demanding applications. The valve offers closed transitions between positions B and R, enhancing performance by providing faster and more consistent response times, especially beneficial in pilot control applications where capacity is less critical. The manual override options available with the D or L control include a detent mechanism designed for temporary actuation, supporting up to approximately 7,000 cycles. For compatibility with different fluid types, cartridges configured with EPDM seals are specifically intended for use with phosphate ester fluids; however, they should not be exposed to petroleum-based fluids which can damage the seals. The wet armature design incorporated into this model allows the working fluid to surround the armature, which helps manage heat during prolonged coil energization but requires consideration of fluid type to avoid degradation. Interchangeability of coils with other Sun Series 1 solenoid products adds versatility to this model, allowing for flexible installation orientations. Additionally, the Sun floating style construction minimizes internal parts binding that could result from excessive installation torque or cavity/cartridge machining variations. This valve is capable of handling flow rates up to 12 gpm (45 L/min) and can withstand operating pressures up to 5000 psi (350 bar), offering both reliability and high capacity in hydraulic system operations.
