The Sun Hydraulics DMDAXNN236 (DMDAXNN236) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is specifically designed to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). Notably, the solenoid tube assembly of this model is fatigue rated for demanding applications, ensuring durability and reliability under high-pressure conditions. The DMDAXNN236 features closed transitions between spool positions B and R, enhancing performance by providing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. This valve does not require a minimum hydraulic pressure for operation, making it versatile in various hydraulic systems. It incorporates a wet armature design where the working fluid surrounds the armature; this design consideration is crucial when the coil is energized for extended periods as it influences fluid integrity over time. Interchangeable coils with other Sun Series 1 solenoid products add to the flexibility of this model, allowing for easy maintenance and replacement. The construction includes Sun\u2019s floating style design which minimizes internal parts binding \u2014 a common issue caused by excessive installation torque or cavity/cartridge machining variations. Additional features such as manual override capabilities are included with detent mechanisms designed for temporary actuation. The manual control assembly has a mechanical life expectancy of about 7,000 cycles. For environments using phosphate ester fluids, cartridges configured with EPDM seals are recommended to prevent damage from petroleum-based substances. Overall, the Sun Hydraulics DMDAXNN236 valve offers robust performance with its advanced engineering tailored for efficient directional control in hydraulic systems requiring precise operation under high pressure and varied fluid 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.
