The Sun Hydraulics DNDATHV72419 (DNDATHV72419) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting and balanced spool directional control. It features a solenoid tube assembly with a fatigue rating suited for 5000 psi (350 bar) service, ensuring durability under high-pressure conditions. This valve operates without the need for minimum hydraulic pressure and offers several manual override options, though compatibility with weatherized coils is limited. The manual override mechanism, available on specific models with D or L control, is intended for temporary actuation and has an estimated mechanical life of about 7,000 cycles. The valve is constructed to accommodate EPDM seals suitable for phosphate ester fluid systems but may degrade if exposed to petroleum-based substances. Its wet armature design allows the working fluid to surround the armature, which can affect performance if the coil remains energized over extended periods due to heat generation. The DNDATHV72419 valve provides various coil termination and voltage configurations, including options with surge protection. It incorporates a high-efficiency solenoid design that maximizes spool actuating force per watt used, enhancing reliability in valve shifting. Coils are compatible with other Sun Series 1 products and can be installed in either direction on the tube. Connector options offer protection ratings up to IP69K for enhanced environmental resilience. The cartridge utilizes Sun\u2019s floating style construction to reduce internal binding risks due to installation torque or machining variations. Key specifications include a T31A cavity type, Series 1 classification, a capacity of 10 gpm (40 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum leakage of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). The valve supports switching frequencies up to 15,000 cycles per hour and requires manual override force of approximately 5 lbs/1000 psi at Port 1.
