The Sun Hydraulics DMDAMRN224N (DMDAMRN224N) is a solenoid-operated 3-way, 2-position cartridge valve that exemplifies high performance and reliability in hydraulic systems. This direct-acting, balanced spool directional valve is designed to operate without minimum hydraulic pressure and features a fatigue rating for 5000 psi (350 bar) service, making it suitable for high-pressure applications. The valve's spools B and R remain closed during the transition between positions, which enhances performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. Equipped with EPDM seals, the DMDAMRN224N 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 incorporates a wet armature design where the working fluid surrounds the armature. This design consideration is crucial as prolonged energization of the coil can lead to higher fluid temperatures which may degrade certain types of hydraulic fluids. For manual override operations, models with D or L control feature a detent mechanism designed for temporary actuation with a mechanical life expectancy of around 7,000 cycles. Additionally, this model boasts interchangeable coils compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. This product also benefits from Sun's floating style construction that minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With specifications including a maximum operating pressure of 5000 psi (350 bar), flow capacity of 12 gpm (45 L/min), and typical response time of 50 ms, the DMDAMRN224N is an efficient solution for various hydraulic control applications requiring robust and precise fluid management.
