The Sun Hydraulics DMDAMBN528 (DMDAMBN528) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for rigorous industrial applications. This direct-acting, balanced spool directional valve operates with a maximum pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min). The valve features a unique wet armature design where the working fluid surrounds the armature, potentially affecting fluid properties under prolonged energization. It is equipped with EPDM seals suitable for phosphate ester fluids, but these seals are vulnerable to damage from petroleum-based fluids. This model's manual override includes a detent mechanism designed for temporary actuation with an estimated mechanical life of about 7,000 cycles. Transitioning between positions, spools B and R remain closed, enhancing performance by ensuring faster and more consistent response times at the cost of reduced capacity, which is particularly advantageous in pilot control applications where capacity is less critical. The DMDAMBN528 also boasts interchangeable coils compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Its construction incorporates Sun\u2019s floating style to reduce internal part binding due to installation torque or cavity/cartridge machining variations. Key specifications include a typical response time of 50 ms and a switching frequency capable of reaching up to 15,000 cycles per hour. The manual override requires minimal force and has a modest stroke length for ease of operation under various pressure settings. This robust design ensures reliable operation and adaptability across diverse hydraulic systems.

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.
