The Sun Hydraulics DMDAXRN648 (DMDAXRN648) 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 is fatigue rated for the same, ensuring durability and reliability in demanding applications. It features a closed transition between spools B and R to enhance performance by providing faster and more consistent response times, particularly suitable for pilot controls where capacity is less critical. The DMDAXRN648 requires no minimum hydraulic pressure to operate, making it highly versatile across various hydraulic systems. It incorporates a wet armature design where the working fluid surrounds the armature, potentially affecting fluid integrity under prolonged energization. This valve is compatible with EPDM seals intended for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they could degrade. Additionally, this model offers interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The manual override feature included in models with D or L control uses a detent mechanism designed for temporary actuation with an expected mechanical life of about 7,000 cycles. The valve also showcases Sun's floating style construction which minimizes internal part binding due to installation torque or cavity/cartridge machining variations. With a flow capacity of up to 12 gpm (45 L/min), typical response time of 50 ms, and maximum leakage at 3000 psi not exceeding 5 in\u00b3/min., the DMDAXRN648 proves efficient for various hydraulic applications requiring precise control and rapid switching (up to 15,000 cycles/hr). Its robust design coupled with versatile configuration options makes it suitable for complex hydraulic systems 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.
