The Sun Hydraulics DMDAXAN736 (DMDAXAN736) is a solenoid-operated 3-way, 2-position cartridge that functions as a direct-acting, balanced spool directional valve. Designed for high-pressure applications, this valve can handle up to 5000 psi (350 bar), making it suitable for various hydraulic systems. It features a quick response time of typically 50 ms and has a maximum flow capacity of 12 gpm (45 L/min). The valve is unique in its closed transition between positions B and R, which enhances performance by ensuring faster and more consistent response times, particularly useful in pilot control applications where flow capacity is less critical. This model incorporates a wet armature design allowing the working fluid to surround the armature, which can be essential when considering the thermal management of the system. The DMDAXAN736 also supports interchangeable coils with other Sun Series 1 solenoid products, providing flexibility in maintenance and replacement processes. It includes EPDM seals suitable for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they could degrade. Additional features include a manual override function with a detent mechanism designed for temporary actuation and an expected mechanical life of about 7,000 cycles. The manual override requires minimal force (5 lbs at 1000 psi for Port 1) and has a stroke length of .10 inches. For installation, this valve demands specific torque settings between 30 \u2013 35 lbf-ft and features Sun's floating style construction to minimize internal binding due to installation stresses or cavity/cartridge machining variations. This robust construction along with its switching frequency capability of up to 15,000 cycles per hour makes the DMDAXAN736 an efficient choice for demanding hydraulic applications requiring reliable directional control.

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.
