The Sun Hydraulics DNDAMYN636 (DNDAMYN636) is a solenoid-operated, 4-way, 2-position cartridge valve, designed for direct-acting applications with a balanced spool directional configuration. This valve is engineered for high-performance operations, featuring a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar) service pressure. It operates independently of hydraulic pressure, making it versatile for various applications. The valve accommodates several manual override options; however, weatherized coils are not compatible with these overrides. The manual override's detent mechanism is designed for temporary actuation with an estimated mechanical life expectancy of approximately 7,000 cycles. EPDM seals are included for systems utilizing phosphate ester fluids, but they should be protected from petroleum-based substances to avoid damage. This cartridge incorporates a wet armature design where the working fluid surrounds the armature and absorbs the heat generated by the coil. It\u2019s crucial to note that certain fluids like water-glycol mixtures may degrade over time at elevated temperatures. A variety of coil termination and voltage options are available, offering flexibility in electrical configurations and surge protection features. The solenoid\u2019s magnetic design ensures high efficiency by delivering substantial spool actuating force per watt consumed, ensuring reliable shifting performance. The valve's construction features Sun's floating style to reduce internal part binding due to installation torque or machining variations. It fits into cavity T-31A and belongs to Series 1 with a capacity of 10 gpm (40 L/min). The valve has a rapid response time of about 50 ms and can handle switching frequencies up to 15,000 cycles per hour with minimal leakage at specified conditions. Installation requires a torque between 30-35 lbf-ft (41-47 Nm), and it weighs approximately .60 lb (0.30 kg). For maintenance or replacement needs, Viton seal kits are available for both the cartridge and coil components.
