The Sun Hydraulics DMDADPN528 (DMDADPN528) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve features a robust design that ensures reliability and durability under demanding conditions. The solenoid tube assembly is fatigue rated for up to 5000 psi (350 bar), suitable for high-pressure applications. The DMDADPN528 provides precise control with spools B and R maintaining closed positions during transitions, enhancing performance by ensuring faster and more consistent response times. This characteristic makes the valve particularly effective when used as pilot controls where capacity is less critical. Additionally, the valve operates without requiring a minimum hydraulic pressure, allowing for flexible installation across various system configurations. For manual override operations, the model equipped with D or L control features a detent mechanism designed for temporary actuation, with a mechanical life expectancy of around 7,000 cycles. The cartridge uses EPDM seals configured specifically for systems using phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. Another key feature includes its wet armature design where the working fluid surrounds the armature. This design consideration is crucial as prolonged coil energization can lead to fluid breakdown in certain types of fluids like water-glycol mixtures. The interchangeable coils compatible with other Sun Series 1 solenoid products offer additional versatility and ease of maintenance. Incorporating Sun\u2019s floating style construction minimizes internal parts binding due to installation torque or machining variations of cavity/cartridge. With a flow capacity of 12 gpm (45 L/min) and maximum operating pressure of 5000 psi (350 bar), the DMDADPN528 is an efficient solution for high-performance hydraulic systems requiring reliable directional 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.
