The Sun Hydraulics DMDAMPN948 (DMDAMPN948) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust service with a fatigue rating for up to 5000 psi (350 bar). The valve features a closed transition between Spools B and R, enhancing performance by ensuring faster and more consistent response times, particularly suitable for applications where capacity is not critical but speed and reliability are essential. The DMDAMPN948 operates without requiring a minimum hydraulic pressure, adding versatility across various hydraulic systems. It includes optional manual overrides (D, L, or T control types), with a mechanical life expectancy of about 7,000 cycles. This model is particularly sensitive to the type of fluid used; cartridges with EPDM seals are specifically intended for systems using phosphate ester fluids and must avoid exposure to petroleum-based fluids to prevent seal damage. Additionally, the valve incorporates a wet armature design allowing the working fluid to cool the armature, although prolonged energization should be monitored as it can degrade certain fluid types. The interchangeable coils are compatible with other Sun Series 1 solenoid products and can be mounted in either direction for increased adaptability. The construction utilizes Sun's floating style to minimize internal part binding due to installation variances or cavity/cartridge machining errors. With specifications including a maximum flow capacity of 12 gpm (45 L/min) and rapid response times typically around 50 ms, this valve is designed for efficient operation in demanding environments. Its compact size (.60 lb/0.30 kg) and the ability to handle switching frequencies up to 15,000 cycles/hr make it an ideal choice for high-cycle applications requiring precise control and reliability.
