The Sun Hydraulics DMDAMRN814 (DMDAMRN814) is a highly efficient, solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This model is particularly noted for its robust construction which includes a solenoid tube assembly rated for fatigue at 5000 psi (350 bar), making it suitable for high-pressure applications. The valve operates with no minimum hydraulic pressure required, ensuring reliable functionality under a variety of conditions. The DMDAMRN814 incorporates closed transitions between Spools B and R, enhancing performance by allowing faster and more consistent response times when used as pilot controls. This configuration is ideal where capacity is less critical but speed and precision are necessary. Additionally, the valve features interchangeable coils with other Sun Series 1 solenoid products, providing flexibility in maintenance and replacement tasks. This model also benefits from Sun's floating style construction which minimizes internal part binding due to installation torque or variations in cavity/cartridge machining. The manual override mechanism on models equipped with D or L control is designed for temporary actuation and has a mechanical life expectancy of about 7,000 cycles. For environments utilizing phosphate ester fluids, cartridges configured with EPDM seals are recommended to prevent damage from petroleum-based substances. The wet armature design allows the working fluid to surround the armature which could be a consideration if the coil remains energized over extended periods; this exposure can degrade certain types of hydraulic fluids. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and typical response times around 50 ms. The valve's overall design and capabilities make it an excellent choice for applications requiring precise control with high reliability in demanding operational conditions.

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.
