The Sun Hydraulics DMDATPN514 (DMDATPN514) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve operates without minimum hydraulic pressure and features a fatigue rating for services up to 5000 psi (350 bar). The design includes closed spools B and R during transition, which enhances performance by providing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. The DMDATPN514 model incorporates a wet armature design, meaning the working fluid surrounds the armature, potentially affecting fluid characteristics if the coil remains energized over extended periods. This valve supports a maximum flow capacity of 12 gpm (45 L/min) and offers swift response times typically around 50 ms. It comes with interchangeable coils compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additional durability is provided through its floating style construction which helps minimize internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. The manual override feature requires a force of about 5 lbs at 1000 psi for port 1 activation and incorporates a detent mechanism designed for temporary actuation with an estimated mechanical life of about 7,000 cycles. Suitable for use with phosphate ester fluids when equipped with EPDM seals, this model ensures robust performance across various applications while maintaining stringent leakage controls at maximum operating pressures.
