The Sun Hydraulics DMDATAV814N (DMDATAV814N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. It features a direct-acting, balanced spool design that ensures reliable control in various hydraulic systems. The valve operates with a maximum capacity of 12 gpm (45 L/min) and can withstand an operating pressure up to 5000 psi (350 bar). Its rapid response time of approximately 50 ms makes it suitable for applications requiring quick actuation. This model\u2019s construction includes a fatigue-rated solenoid tube assembly designed for heavy-duty use, and its spools (B and R) are closed during the transition between positions to enhance performance. The valve does not require a minimum hydraulic pressure to function, making it versatile in different operational contexts. Additionally, the DMDATAV814N incorporates EPDM seals suitable for use with phosphate ester fluids, although these seals are vulnerable to petroleum-based products. For manual operation, the valve includes a detent mechanism in its manual override that is intended for temporary actuation with an expected mechanical life of about 7,000 cycles. The wet armature design of the valve means that it should be monitored when energized over long periods due to potential heat effects on certain hydraulic fluids. Sun Hydraulics has also designed this model with interchangeable coils compatible with other Series 1 solenoid products and has incorporated their floating style construction to minimize internal binding risks from installation issues or cavity/cartridge machining variations. This makes the DMDATAV814N not only robust but also flexible for integration into diverse hydraulic setups without compromising on reliability or efficiency.

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.
