The Sun Hydraulics DNDAMTV924 (DNDAMTV924) is a solenoid-operated 4-way, 2-position cartridge valve that functions as a direct-acting, balanced spool directional valve. This model features a solenoid tube assembly fatigue-rated for up to 5000 psi (350 bar), ensuring robust performance under high-pressure conditions. It operates without the need for minimum hydraulic pressure and offers various manual override options, although these are incompatible with weatherized coils. The manual controls have a mechanical life expectancy of approximately 7,000 cycles and require specific force for operation. The cartridge is designed with EPDM seals suitable for phosphate ester fluids but can be damaged by petroleum-based substances. This valve incorporates a wet armature design, where the working fluid surrounds the armature and absorbs heat generated by the coil. This factor should be considered in applications involving long periods of coil energization, particularly when using fluids like water-glycol mixtures that may degrade over time due to heat exposure. The solenoid's magnetic design ensures high efficiency, delivering significant spool actuating force per watt and promoting reliable shifting. The DNDAMTV924 supports various coil termination and voltage configurations, including options with surge protection. Coils are interchangeable with other Sun Series 1 products and can be mounted in either direction on the tube. Connector options provide ratings up to IP69K for enhanced environmental protection. The valve's floating style construction minimizes potential binding issues from excessive torque or machining variations. With a capacity of 10 gpm (40 L/min) and maximum leakage at 110 SUS (24 cSt) of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar), this valve is suitable for applications requiring precise flow control and reliability under demanding conditions. Its compact design includes dimensions such as a solenoid tube diameter of .75 inches (19 mm) and installation torque specifications between 30\u201335 lbf\u00b7ft (41\u201347 Nm).
