The Sun Hydraulics DMDAMRN212 (DMDAMRN212) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. Engineered with a balanced spool directional valve mechanism, it operates directly without requiring minimum hydraulic pressure. This model is specifically fatigue rated for demanding 5000 psi (350 bar) service environments, ensuring reliable operation under high-pressure conditions. With its closed spool transitions between positions B and R, the DMDAMRN212 provides enhanced performance limits by maintaining consistent and fast response times, ideal for pilot control applications where capacity is less critical. The valve features a wet armature design, meaning the working fluid surrounds the armature which helps in heat management but requires careful selection of fluid to avoid breakdown and varnish formation. This valve is versatile with its interchangeable coils compatible with other Sun Series 1 solenoid products, which can be mounted in either direction on the tube. It also incorporates Sun\u2019s floating style construction that minimizes internal parts binding due to variations in installation torque or cavity/cartridge machining. Additional specifications include a maximum flow capacity of 12 gpm (45 L/min), typical response times of 50 ms, and maximum leakage at 3000 psi not exceeding 5 in\u00b3/min. The manual override feature requires minimal force and includes detent mechanisms on models with D or L control for temporary actuation. Designed for longevity, the mechanical life expectancy of these manual controls reaches approximately 7,000 cycles. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended to prevent damage from petroleum-based substances. This model\u2019s robust design and interchangeable components make it suitable for various hydraulic applications requiring precise control and reliability.

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.
