The Sun Hydraulics DMDADNV914N (DMDADNV914N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve features a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar), ensuring robust performance in demanding applications. The valve operates with no minimum hydraulic pressure required, making it versatile across various hydraulic systems. Key to its design is the closed transition between Spools B and R, enhancing performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less critical. The DMDADNV914N also incorporates manual override options with a detent mechanism designed for temporary actuation; these are specifically indicated in models equipped with D or L control. This model uses EPDM seals configured for compatibility with phosphate ester fluids, cautioning against use with petroleum-based fluids which could damage the seals. Its wet armature design allows the working fluid to surround the armature, which is beneficial but requires consideration regarding fluid type and operational duration due to potential heat exposure effects. Interchangeability of coils with other Sun Series 1 solenoid products adds flexibility for system design, allowing mounting on the tube in either direction. Additionally, the floating style construction of this valve minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. With a maximum flow capacity of 12 gpm (45 L/min) and rapid typical response time of 50 ms, along with a robust switching frequency of up to 15000 cycles/hr, the DMDADNV914N is suitable for high-cycle applications requiring reliable switching and directional control. This model\u2019s thoughtful engineering ensures it meets stringent operational demands while maintaining efficiency and reliability in hydraulic system implementations.

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.
