The Sun Hydraulics DMDAMRN612N (DMDAMRN612N) 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 features a solenoid tube assembly rated for fatigue at 5000 psi (350 bar), ensuring reliable operation under high-pressure conditions. The valve is particularly noted for its closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less critical. This model's design includes no minimum hydraulic pressure requirement for operation, making it versatile across various hydraulic systems. The manual override options available with the D or L control are designed with a detent mechanism intended for temporary actuation, supporting a mechanical life expectancy of approximately 7,000 cycles. It\u2019s important to note that cartridges with EPDM seals are specifically intended for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. The valve also incorporates a wet armature design where the working fluid surrounds the armature which could be susceptible to heat during prolonged coil energization \u2013 an aspect to consider depending on the hydraulic fluid used. Additionally, the coils of this model are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. For installation ease and reliability, this valve utilizes Sun\u2019s floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With features like a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and swift typical response times around 50 ms, the DMDAMRN612N is engineered for both efficiency and durability in demanding hydraulic applications.

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.
