The Sun Hydraulics DMDADBN736 (DMDADBN736) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic control in various applications. This direct-acting, balanced spool directional valve ensures precise operation with its fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar). It features closed transitions between Spools B and R which optimize performance by providing faster and more consistent response times, especially beneficial in pilot control setups where capacity is less critical. The DMDADBN736 operates without requiring a minimum hydraulic pressure and incorporates a wet armature design that surrounds the armature with working fluid, vital for managing the heat generated by the coil during prolonged energization. This design consideration is crucial as certain fluids like water-glycol mixtures might degrade under sustained high temperatures. The valve's manual override mechanism, equipped in models with D or L control, is designed for temporary actuation with a mechanical life expectancy of about 7,000 cycles. Additionally, this model uses EPDM seals suitable for systems utilizing phosphate ester fluids while being incompatible with petroleum-based fluids which can damage the seals. Interchangeable coils from Sun Series 1 solenoid products add versatility to this unit, allowing for easy maintenance and replacement. The construction also features Sun's floating style to minimize internal part binding due to installation torque or cavity/cartridge machining variations. Key specifications include a maximum flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and a manual override requirement of only 5 lbs at 1000 psi at Port 1. The compact form factor weighs just 0.60 lb (0.30 kg), making it suitable for various installation environments without adding significant weight or bulk.
