The Sun Hydraulics DMDADPN912 (DMDADPN912) 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 activation. It features a robust design with a fatigue rating for 5000 psi (350 bar) service, making it suitable for demanding applications. The DMDADPN912 valve incorporates closed transitions between positions B and R, enhancing performance by ensuring faster and more consistent response times, particularly useful in pilot control applications where capacity is less critical. The valve\u2019s wet armature design allows the working fluid to surround the armature, which is beneficial for heat dissipation but requires consideration of fluid characteristics as some may degrade under prolonged exposure to heat. This model is compatible with EPDM seals specifically designed for use with phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. The manual override feature included in models equipped with D or L control is intended for temporary actuation and has a mechanical life expectancy of about 7,000 cycles. Furthermore, the DMDADPN912 can handle a flow capacity of up to 12 gpm (45 L/min) and features interchangeable coils that are common with other Sun Series 1 solenoid products. The construction includes Sun\u2019s floating style design which minimizes internal part binding due to installation torque or machining variances of cavity/cartridge. This model also supports a maximum operating pressure of 5000 psi (350 bar) and offers rapid response times typically around 50 ms.
