The Sun Hydraulics DMDAXPV214N (DMDAXPV214N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust and efficient hydraulic control. This direct-acting, balanced spool directional valve is specifically engineered to handle a maximum operating pressure of 5000 psi (350 bar), making it suitable for high-pressure applications. The valve features a unique closed transition between spools B and R, enhancing performance by ensuring faster and more consistent response times, particularly beneficial when used as pilot controls where flow capacity is less critical. With its direct actuation, the DMDAXPV214N requires no minimum hydraulic pressure to operate, providing flexibility across various hydraulic systems. It includes manual override options with the D or L control for temporary actuation, supported by a detent mechanism designed to withstand approximately 7,000 cycles. Additionally, the valve employs EPDM seals ideal for phosphate ester fluids but must avoid exposure to petroleum-based substances to prevent seal damage. This model also incorporates a wet armature design where the working fluid surrounds the armature. This design consideration is crucial as prolonged energization can lead to fluid degradation at elevated temperatures. For compatibility and maintenance ease, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Constructed with Sun's floating style construction, the DMDAXPV214N minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. With a flow capacity of 12 gpm (45 L/min) and rapid typical response times of 50 ms, this valve ensures efficient operation while maintaining leakage at minimal levels under maximum pressure conditions. The cartridge's robust design and interchangeable components make it an adaptable solution for demanding hydraulic control applications.
