The Sun Hydraulics DMDADRV214N (DMDADRV214N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve ensures reliable operation with its fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar). The valve features closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, especially suitable for applications where capacity is not a critical factor. This model is particularly noted for its robust design which includes a wet armature setup. The working fluid envelops the armature, mitigating the risk of overheating even when the coil is energized over extended periods. However, it's important to note that certain fluids like water-glycol mixtures may degrade under prolonged exposure to heat, potentially impacting valve performance. Additionally, the DMDADRV214N can be equipped with EPDM seals specifically for use with phosphate ester fluids; however, these seals are incompatible with petroleum-based fluids. Users will find flexibility in installation and maintenance as the coils of this valve are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction. With a maximum flow capacity of 12 gpm (45 L/min) and a typical response time of 50 ms, this valve is an efficient choice for various hydraulic applications. It also features manual override options with a mechanical life expectancy of about 7,000 cycles, ensuring reliable manual control when needed. The construction incorporates Sun\u2019s floating style design to minimize internal parts binding due to installation variances or machining discrepancies. Ideal for systems requiring precise control and rapid response times without significant fluid capacity needs, the DMDADRV214N offers durability and versatility in challenging industrial environments.

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.
