The Sun Hydraulics DMDATNV512 (DMDATNV512) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve features a robust design with spools B and R that are closed in the transition between their two positions, optimizing performance by providing faster and more consistent response times especially in pilot control applications where capacity is less critical. The valve operates without requiring a minimum hydraulic pressure, enhancing its versatility across various hydraulic applications. Equipped with fatigue-rated solenoid tube assemblies for up to 5000 psi (350 bar) service, the DMDATNV512 ensures reliability even under extreme conditions. It incorporates Sun's floating style construction which minimizes internal parts binding due to excessive installation torque or cavity/cartridge machining variations. Additionally, the manual override feature in models with D or L control is specifically designed for temporary actuation with a mechanical life expectancy of about 7,000 cycles. The valve's wet armature design allows the working fluid to surround the armature, which can be crucial when considering the type of fluid used due to potential breakdowns from prolonged heat exposure. It uses EPDM seals suitable for systems with phosphate ester fluids while being incompatible with petroleum-based fluids which can damage the seals. The valve also supports interchangeable coils with other Sun Series 1 solenoid products, offering flexibility in system design and maintenance. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity of up to 12 gpm (45 L/min), and typical response time of 50 ms. Its compact form factor and capability to switch up to 15,000 cycles per hour make it an efficient choice for dynamic systems requiring precise control and durability.
