The Sun Hydraulics DMDAXAN628 (DMDAXAN628) is a high-performance solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool design ideal for various hydraulic applications. With a robust construction rated for fatigue at 5000 psi (350 bar), this valve ensures reliable operation under high-pressure conditions. The unique closed transition between Spools B and R during operation enhances performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. This valve operates without the need for minimum hydraulic pressure, adding to its versatility in different system configurations. It includes options for manual override controls (D, L, T types), which are designed primarily for temporary actuation with a mechanical life expectancy of around 7,000 cycles. Special attention is given to its compatibility with EPDM seals configured for phosphate ester fluids, while caution is advised against exposure to petroleum-based fluids which may damage the seals. Featuring a wet armature design, the DMDAXAN628 allows the working fluid to surround the armature which might be susceptible to heat during prolonged coil energization; this could lead to fluid degradation in certain conditions. Interchangeability of coils with other Sun Series 1 solenoid products offers flexibility and ease of maintenance while ensuring correct installation through its floating style construction that minimizes internal binding due to torque or machining variations. The valve supports a flow capacity of up to 12 gpm (45 L/min) and includes specifications like a typical response time of 50 ms and maximum leakage at 3000 psi not exceeding 5 in\u00b3/min. It also features manual override specifications such as force requirements and stroke distances that ensure ease of manual operation when necessary. This model\u2019s practical design considerations make it suitable for various industrial applications requiring precise hydraulic flow 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.
