The Sun Hydraulics DMDADAV612N (DMDADAV612N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve, featuring a direct-acting, balanced spool design. This valve is particularly noted for its robust construction which includes a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar). It is engineered for precise control with closed transitions between spool positions B and R, enhancing performance by ensuring faster and more consistent response times especially suitable for applications requiring pilot controls. This model operates without the need for minimum hydraulic pressure, thereby providing flexibility in various hydraulic systems. The DMDADAV612N also includes optional manual override controls (D, L, and T types) which are designed primarily for temporary actuation with a mechanical life expectancy of around 7,000 cycles. The valve incorporates EPDM seals configured specifically for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. The wet armature design of this valve ensures the working fluid surrounds the armature which could be significant in applications where the coil remains energized over extended periods. Potential issues such as breakdown of certain fluids like water-glycol mixtures at high temperatures are mitigated by this design. Additionally, the interchangeable coils compatible with other Sun Series 1 solenoid products offer versatility and ease of maintenance. Featuring the Sun floating style construction minimizes internal parts binding due to installation torque or machining variations in cavity/cartridge. This cartridge valve is suitable for systems requiring reliable and efficient directional control of fluid flow with minimal leakage and can handle up to 12 gpm (45 L/min) capacity at maximum operating pressures.
