The Sun Hydraulics DMDATNN223 (DMDATNN223) is a precision-engineered solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve ensures reliable control in various applications, featuring a fatigue rating for 5000 psi (350 bar) service, making it suitable for demanding environments. The valve's spools (B and R) are closed during the transition between positions to enhance performance limits while sacrificing some capacity, which is not a concern when used as pilot controls due to the faster and more consistent response times achieved. Not requiring any minimum hydraulic pressure for operation, the DMDATNN223 valve is directly actuated. It includes manual override options with detent mechanisms designed for temporary actuation, with a mechanical life expectancy of around 7,000 cycles. The wet armature design of this model means that the working fluid surrounds the armature; this exposure can affect fluid integrity under prolonged energization and should be considered when using certain fluids like water-glycol mixtures. This versatile cartridge can be configured with EPDM seals specifically for use with phosphate ester fluids; however, exposure to petroleum-based substances should be avoided as it would compromise the seal integrity. With interchangeable coils that fit other Sun Series 1 solenoid products and can be mounted in either direction on the tube, this valve also incorporates Sun's floating style construction to minimize internal part binding from installation torque or cavity/cartridge machining variations. The DMDATNN223 offers a maximum operating pressure of 5000 psi (350 bar), a flow capacity of up to 12 gpm (45 L/min), and typical response times of around 50 ms. Its design ensures minimal leakage and supports switching frequencies up to 15,000 cycles per hour. These features make it an adaptable solution for sophisticated hydraulic setups requiring precise fluid control and robust performance.
