The Sun Hydraulics DMDAXPN836 (DMDAXPN836) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for use in advanced hydraulic systems. This direct-acting, balanced spool directional valve operates with no minimum hydraulic pressure required, making it versatile across a range of applications. It features a fatigue-rated solenoid tube assembly for services up to 5000 psi (350 bar), ensuring durability and reliability under rigorous conditions. The valve's design incorporates closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times especially when used as pilot controls. This feature is particularly beneficial where capacity is not a critical factor but speed and precision are necessary. The model also includes manual override options with the D or L control having a detent mechanism designed for temporary actuation, supporting about 7,000 mechanical life cycles. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended to avoid damage from petroleum-based substances. The wet armature design of the valve allows the working fluid to surround the armature which can be significant if the coil remains energized for extended periods; this could lead to breakdowns in certain fluids at elevated temperatures. Furthermore, the DMDAXPN836 is compatible with other Sun Series 1 solenoid products regarding interchangeable coils which can be mounted in either orientation on the tube. It also features Sun\u2019s floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With a capacity of up to 12 gpm (45 L/min) and quick response times typically around 50 ms, this valve is an efficient solution for managing directional control in hydraulic circuits requiring robustness and precision.

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.
