The Sun Hydraulics DMDAXNN948 (DMDAXNN948) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust and precise hydraulic control. This direct-acting, balanced spool directional valve ensures reliable operation with no minimum hydraulic pressure required for activation. The valve features a fatigue-rated solenoid tube assembly for services up to 5000 psi (350 bar), making it suitable for demanding applications. Capable of handling fluid capacities up to 12 gpm (45 L/min) and operating pressures as high as 5000 psi (350 bar), the DMDAXNN948 exhibits a rapid response time of approximately 50 ms. It is engineered with closed transitions between spool positions B and R, enhancing performance by ensuring faster and more consistent response times, particularly useful in pilot control applications where capacity is less critical. This model incorporates EPDM seals specifically for use with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. The wet armature design allows the working fluid to surround the armature which could be subjected to heat during prolonged coil energization\u2014important to consider when using certain hydraulic fluids. Additionally, the DMDAXNN948 features interchangeable coils compatible with other Sun Series 1 solenoid products and includes manual override options with a mechanical life expectancy of around 7,000 cycles. For ease of installation and maintenance, it uses Sun's floating style construction which minimizes internal parts binding due to installation torque or machining variations. This makes the DMDAXNN948 an adaptable solution ideal for various hydraulic system applications requiring precise directional control and durability.

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.
