The Sun Hydraulics DMDADPN224 (DMDADPN224) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is engineered to operate without minimum hydraulic pressure, making it highly versatile for various applications. It features a fatigue rating for 5000 psi (350 bar) service, ensuring durability and reliability in demanding environments. The DMDADPN224 valve incorporates a closed transition between Spools B and R, enhancing performance by providing faster and more consistent response times especially when used as pilot controls. This design characteristic makes the valve suitable for applications where rapid actuation and precision are critical. Furthermore, the manual override options available with this model include detent mechanisms (D or L control) intended for temporary actuation only, with a mechanical life expectancy of about 7,000 cycles. Equipped with EPDM seals, the DMDADPN224 is specifically configured for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. The valve also utilizes a wet armature design where the working fluid surrounds the armature which can be a consideration if the coil remains energized over extended periods potentially leading to fluid degradation. This model boasts interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, it features Sun's floating style construction that minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. With a maximum operating capacity of 12 gpm (45 L/min) and quick response times typically around 50 ms, this valve is an excellent choice for sophisticated hydraulic control systems requiring high switching frequencies up to 15,000 cycles/hr.
