The Sun Hydraulics DMDAXAVHN24AA (DMDAXAVHN24AA) is a solenoid-operated, 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve is notable for its robust construction and high-performance capabilities. It operates without the need for a minimum hydraulic pressure, making it versatile across various applications. The valve features closed transitions between spool positions B and R, enhancing performance by ensuring faster and more consistent response times, especially suitable for pilot control systems where capacity is less critical. The unit is fatigue-rated for up to 5000 psi (350 bar), and includes a solenoid tube assembly rated similarly for high-pressure service environments. The DMDAXAVHN24AA can handle a maximum flow capacity of 12 gpm (45 L/min) and features quick response times typically around 50 ms. For maintenance or manual operation, it includes a manual override with a detent mechanism designed to withstand approximately 7,000 cycles. This model incorporates EPDM seals suitable for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they could degrade. The wet armature design of the valve allows the working fluid to surround the armature which aids in heat management but requires consideration regarding fluid selection to prevent breakdown or varnish formation. Interchangeability of coils with other Sun Series 1 solenoid products adds to the flexibility of this model, allowing users to adapt or replace parts with ease. Additionally, Sun Hydraulics employs a floating style construction in this model which minimizes internal binding caused by installation torque or machining variations in the cavity/cartridge setup. This design consideration extends the reliability and longevity of the valve in demanding operational conditions.

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.
