The Sun Hydraulics DMDAXBV628 (DMDAXBV628) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for direct-acting operation with a balanced spool directional control mechanism. This model is particularly noted for its robust construction that includes a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar). The valve features closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times, ideal for applications requiring precise control such as pilot operations where capacity is not the primary concern. The DMDAXBV628 operates without the need for minimum hydraulic pressure, adding to its versatility in various system configurations. It includes options for manual overrides with detent mechanisms designed for temporary actuation, supporting mechanical life expectancies of around 7,000 cycles. Additionally, this valve model is equipped with EPDM seals suitable for systems using phosphate ester fluids; however, these seals must avoid exposure to petroleum-based fluids which can cause damage. Another key feature of the DMDAXBV628 is its wet armature design where the working fluid surrounds the armature. This design consideration is crucial when the coil remains energized over extended periods as it can affect fluid integrity due to heat exposure. The valve also boasts interchangeable coils compatible with other Sun Series 1 solenoid products and incorporates Sun\u2019s floating style construction to minimize internal parts binding caused by installation torque or machining variations of cavity/cartridge. With specifications including a maximum flow capacity of 12 gpm (45 L/min), typical response times of 50 ms, and maximum operating pressures up to 5000 psi (350 bar), this valve ensures reliable performance and durability in demanding applications. Additionally, it supports a high switching frequency up to 15,000 cycles/hr and requires manual override force of just 5 lbs at 1000 psi on Port 1. The compact design also features a .75 in (19 mm) solenoid tube diameter and weighs approximately .60 lb (0.30 kg), making it an efficient choice for space-constrained installations.

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.
