The Sun Hydraulics DMDAXBN636 (DMDAXBN636) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve features a fatigue rating of 5000 psi (350 bar), making it suitable for rigorous applications. The valve incorporates closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times, particularly useful in pilot control applications where capacity is less critical. The DMDAXBN636 operates without requiring a minimum hydraulic pressure, which allows for flexibility in various system configurations. It includes options for manual overrides with the D or L control, designed primarily for temporary actuation with a mechanical life expectancy of about 7,000 cycles. The valve's construction uses EPDM seals specifically for systems utilizing phosphate ester fluids; however, these seals are vulnerable to damage if exposed to petroleum-based fluids. One notable feature of the DMDAXBN636 is its wet armature design where the working fluid surrounds the armature. This design can impact fluid integrity if the coil remains energized over extended periods due to heat exposure. Additionally, it offers interchangeable coils compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. This model also benefits from Sun's floating style construction which minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With a maximum operating pressure of 5000 psi (350 bar) and a capacity of 12 gpm (45 L/min), the Sun Hydraulics DMDAXBN636 is engineered to meet demanding hydraulic control requirements efficiently and reliably.

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.
