The Sun Hydraulics DMDATPN228 (DMDATPN228) is a solenoid-operated 3-way, 2-position cartridge valve designed with a direct-acting, balanced spool for efficient directional control in hydraulic systems. This model features a robust construction that is fatigue rated for 5000 psi (350 bar), making it suitable for high-pressure applications. The valve exhibits closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times, particularly beneficial in pilot control setups where capacity is less critical. The DMDATPN228 operates without requiring a minimum hydraulic pressure, adding to its versatility across various applications. It includes options such as the D or L control with a manual override detent mechanism designed for temporary actuation and has an estimated mechanical life of about 7,000 cycles. The valve is compatible with EPDM seals specifically for use with phosphate ester fluids; however, these seals must avoid exposure to petroleum-based fluids which could cause damage. Additionally, the valve's wet armature design allows the working fluid to surround the armature, which could be significant in scenarios where the coil remains energized over extended periods as it affects fluid integrity due to heat exposure. The interchangeable coils are another feature that adds flexibility and ease of maintenance by being compatible with other Sun Series 1 solenoid products. For installation convenience, this model incorporates Sun's floating style construction which minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With a capacity of 12 gpm (45 L/min) and quick response times typically around 50 ms, the DMDATPN228 provides reliable performance and operational efficiency suitable for a variety of hydraulic system applications.
