The Sun Hydraulics DMDAMBV528 (DMDAMBV528) is a solenoid-operated, 3-way, 2-position cartridge valve featuring a direct-acting, balanced spool directional design. Engineered for high-performance applications, this valve is capable of operating with no minimum hydraulic pressure required. Its solenoid tube assembly is fatigue-rated for up to 5000 psi (350 bar), ensuring reliability under rigorous conditions. The DMDAMBV528 facilitates closed transitions between Spools B and R to enhance performance limits at the cost of lower capacity, making it ideal for pilot control applications where rapid and consistent response times are critical. This model incorporates a wet armature design where the working fluid surrounds the armature, potentially affecting fluid properties if the coil remains energized over extended periods. It is compatible with EPDM seals specifically designed for use with phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based substances. Notably versatile in its construction, the DMDAMBV528's coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The valve also features a manual override mechanism intended for temporary actuation with a mechanical life expectancy of around 7,000 cycles. For installations requiring precision and durability, it employs Sun\u2019s floating style construction which minimizes internal part binding due to excessive installation torque or cavity/cartridge machining variations. Key specifications include a flow capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum valve leakage at 5 in\u00b3/min at 3000 psi. The DMDAMBV528 also supports switching frequencies up to 15,000 cycles/hr and requires manual override force of about 5 lbs at 1000 psi per port. This model weighs approximately 0.60 lb (0.30 kg) and has specific dimensions for installation including a solenoid tube diameter of .75 in (19 mm) and valve hex size of .875 in (22.2 mm).

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.
