The Sun Hydraulics DMDAXRV212N (DMDAXRV212N) 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 fatigue rating of 5000 psi (350 bar), making it suitable for high-pressure environments. The DMDAXRV212N model is engineered with closed transitions between Spools B and R to enhance performance by ensuring faster and more consistent response times, particularly useful in pilot control applications where capacity is less critical. This valve operates without requiring a minimum hydraulic pressure, offering flexibility in various operating conditions. It includes manual override options with the D, L, and T control assemblies, which are designed to sustain approximately 7,000 cycles of mechanical life. The use of EPDM seals in cartridges specifies compatibility with phosphate ester fluids while cautioning against exposure to petroleum-based substances that could degrade the seals. Additionally, the DMDAXRV212N utilizes a wet armature design where the working fluid surrounds the armature. This setup aids in cooling but requires consideration regarding fluid selection as some may degrade under prolonged exposure to heat. The interchangeable coils compatible with other Sun Series 1 solenoid products add to its versatility and ease of maintenance. The construction incorporates Sun\u2019s floating style design minimizing internal part binding due to installation variances or excessive torque. With a maximum flow capacity of 12 gpm (45 L/min) and rapid typical response time of 50 ms, this model ensures efficient operation across various applications. Its robust build and thoughtful engineering make it an ideal choice for demanding hydraulic systems requiring reliable directional control and swift actuation.

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.
