The Sun Hydraulics DMDALNN814 (DMDALNN814) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve ensures reliable operation with no minimum hydraulic pressure required for activation. It features a fatigue-rated solenoid tube assembly suitable for up to 5000 psi or 350 bar service, making it ideal for demanding environments. The valve offers precise control with closed transitions between spool positions B and R, enhancing performance by providing faster and more consistent response times, particularly useful in pilot control applications where capacity is less critical. The manual override feature incorporated in models with D or L control is designed for temporary actuation and supports around 7,000 cycles of mechanical life expectancy. In terms of construction, the DMDALNN814 utilizes a wet armature design where the working fluid surrounds the armature. This design aspect is crucial as it influences the temperature management within the system, especially when the coil remains energized over extended periods. The valve\u2019s compatibility with EPDM seals makes it suitable for systems using phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided to prevent seal damage. This model also benefits from interchangeable coils within Sun's Series 1 solenoid products and can be mounted in either direction on the tube. It incorporates Sun's floating style construction to minimize internal parts binding due to excessive installation torque or cavity/cartridge machining variations. With a maximum operating capacity of 12 gpm/45 L/min and quick response times typically around 50 ms, along with a robust switching frequency of up to 15,000 cycles/hr, the Sun Hydraulics DMDALNN814 offers an efficient solution for controlling fluid direction in hydraulic systems across various applications.
