The Sun Hydraulics DMDATPN712 (DMDATPN712) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve features a fatigue rating for 5000 psi (350 bar) service, making it suitable for demanding environments. The valve's design includes closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. Notably, the DMDATPN712 requires no minimum hydraulic pressure to operate and incorporates a wet armature design. The surrounding working fluid in the armature helps manage the heat generated by the coil but requires consideration of fluid type to avoid breakdowns that could impair the cartridge's functionality. It supports a flow capacity of up to 12 gpm (45 L/min) and can handle a maximum operating pressure of 5000 psi (350 bar). The typical response time is around 50 ms, with maximum valve leakage specified at 5 in\u00b3/min at 3000 psi. For manual override operations, this model includes a detent mechanism designed for temporary actuation with an expected mechanical life of approximately 7,000 cycles. It also features interchangeable coils compatible with other Sun Series 1 solenoid products and utilizes Sun's floating style construction to minimize internal parts binding. This versatile valve is ideal for systems using phosphate ester fluids when configured with EPDM seals. However, exposure to petroleum-based fluids should be avoided as it can damage the seals. Overall, the DMDATPN712 offers a reliable solution for controlling flow directions in hydraulic systems under various operating conditions.
