The Sun Hydraulics DMDADNN214 (DMDADNN214) is a high-performance solenoid-operated 3-way, 2-position cartridge valve, designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve is distinguished by its robust construction and capability to handle maximum operating pressures up to 5000 psi (350 bar). The valve features a fatigue-rated solenoid tube assembly suitable for demanding applications, ensuring reliability and longevity under high-pressure conditions. One of the notable characteristics of the DMDADNN214 model is its closed transition spools (B and R), which do not allow flow between positions, thereby enhancing performance limits at the cost of reduced capacity. This design trait makes it particularly effective for pilot control applications where speed and consistency of response are more critical than flow capacity. Additionally, this valve operates without requiring a minimum hydraulic pressure, adding to its versatility in various system configurations. The model comes equipped with interchangeable coils that are compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. This interchangeability provides flexibility in installation and maintenance. Furthermore, the wet armature design of the valve ensures that the working fluid surrounds the armature which is crucial when considering thermal management within hydraulic systems. For durability, the manual override feature incorporated within models with D or L control has a mechanical life expectancy of approximately 7,000 cycles. Also important to note are the EPDM seals used in certain configurations; these are specifically chosen for compatibility with phosphate ester fluids while avoiding damage from petroleum-based substances. Overall, Sun Hydraulics\u2019 DMDADNN214 offers a reliable solution for directing flow efficiently in hydraulic systems where precision and durability are required. Its advanced features such as floating style construction minimize internal binding risks due to installation variances or machining discrepancies, further ensuring operational reliability and performance consistency.

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.
