The Sun Hydraulics DMDAMAV528 (DMDAMAV528) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for rigorous hydraulic applications. This direct-acting, balanced spool directional valve excels in environments where high pressure and precise control are required, being rated for up to 5000 psi (350 bar). The valve features a unique closed transition between positions B and R, enhancing performance by ensuring faster and more consistent response times ideal for pilot control applications where capacity is less critical. Equipped with a wet armature design, the DMDAMAV528 allows the working fluid to surround the armature, which helps manage heat generated by the coil but requires careful consideration of fluid type to avoid breakdown and varnish formation. It's compatible with EPDM seals specifically designed for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids which could cause damage. The model also supports interchangeable coils from other Sun Series 1 solenoid products and can be mounted in either direction on the tube. It incorporates Sun\u2019s floating style construction to reduce risks of internal parts binding due to installation variances. The manual override feature included in models with D or L control is intended for temporary actuation, with a mechanical life expectancy of about 7,000 cycles. This valve offers robust switching capabilities up to 15,000 cycles per hour and features a rapid typical response time of 50 ms. With a flow capacity of up to 12 gpm (45 L/min) and minimal leakage at high pressures, the DMDAMAV528 is an effective solution for advanced 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.
