The Sun Hydraulics DMDADRN712N (DMDADRN712N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve is tailored to operate effectively under a maximum pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). The valve's design incorporates a fatigue-rated solenoid tube assembly suitable for demanding operations. The DMDADRN712N features closed transitions between its two positions (Spools B and R), which ensures higher performance limits by reducing capacity only where it is not critical, thus enabling faster and more consistent response times especially in pilot control scenarios. The valve operates without requiring a minimum hydraulic pressure, making it versatile for various applications. Notably, this model includes manual override options with a detent mechanism designed for temporary actuation, offering about 7,000 mechanical life cycles. Designed with EPDM seals, the DMDADRN712N is compatible with systems using phosphate ester fluids; however, it should not be used with petroleum-based fluids as they can damage the seals. Its wet armature design allows the working fluid to surround the armature which helps in heat management but requires consideration regarding fluid stability under prolonged energization. Additionally, the interchangeable coils enhance flexibility and are compatible with other Sun Series 1 solenoid products. Sun Hydraulics has also integrated their floating style construction into this model to minimize internal parts binding that could result from excessive installation torque or variations in cavity/cartridge machining. This thoughtful engineering contributes to the reliability and longevity of the valve in complex hydraulic setups.

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.
