The Sun Hydraulics DMDALPN528 (DMDALPN528) is a solenoid-operated 3-way, 2-position cartridge valve engineered for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is designed to operate without minimum hydraulic pressure, enhancing its reliability and ease of use across various applications. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 12 gpm (45 L/min), it meets the demands of rigorous industrial environments. The DMDALPN528 features a unique wet armature design where the working fluid surrounds the armature, which is critical in managing the heat generated by the coil during prolonged energization. This design consideration is vital for applications where the valve may be energized continuously, as it helps prevent breakdown or varnishing of certain hydraulic fluids like water-glycol mixtures. Additionally, this model incorporates Sun's floating style construction that minimizes internal parts binding due to installation torque or machining variations in cavity/cartridge. This valve model also offers interchangeable coils with other Sun Series 1 solenoid products, providing flexibility and ease of maintenance. The manual override feature included in models equipped with D or L control is specifically designed for temporary actuation, with a mechanical life expectancy of around 7,000 cycles. For environments using phosphate ester fluids, cartridges configured with EPDM seals are recommended to avoid damage from petroleum-based fluids. Overall, the Sun Hydraulics DMDALPN528 stands out for its robust construction, versatile performance capabilities, and thoughtful engineering that accommodates both complex industrial applications and straightforward installations requiring reliable fluid control.

This solenoid-operated 3-way, 2-position cartridge is a direct-acting, balanced spool directional valve.
- The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
- Spools B and R are closed in the transition between their two positions. This results in a higher performance limit at the expense of lower capacity. When used as pilot controls, where capacity is not a factor, the closed transition will provide faster and more consistent response times.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- On models equipped with the D or L control, the detent mechanism in the manual override is meant for temporary actuation. The D, L and T manual control assembly has a mechanical life expectancy of approximately 7,000 cycles.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- This valve utilizes a wet armature design. This means that the working fluid surrounds the armature and is exposed to the heat generated by the coil. This can be a factor if the coil is energized for long periods of time. Some fluids, notably water/glycol mixtures, break down at these temperatures over time and form varnishes that will affect the function of the cartridge.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
