The Sun Hydraulics DMDAMRN514 (DMDAMRN514) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for hydraulic systems. This direct-acting, balanced spool directional valve is notable for its robust design which includes a fatigue-rated solenoid tube assembly capable of handling services up to 5000 psi (350 bar). With spools B and R maintaining a closed position during the transition between two positions, the valve ensures higher performance limits, making it ideal for applications requiring fast and consistent response times without the need for high flow capacity. This model is particularly distinguished by its direct actuation feature that operates without needing a minimum hydraulic pressure, enhancing its efficiency in various systems. The manual override options available with D or L control types are designed for temporary actuation, supporting mechanical life expectancy around 7,000 cycles. It's crucial to note that cartridges with EPDM seals are specifically intended for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. Additionally, the DMDAMRN514 uses a wet armature design where the working fluid surrounds the armature\u2014this design consideration is vital for applications where the coil may be energized continuously. The valve supports interchangeable coils with other Sun Series 1 solenoid products and features a floating style construction to minimize internal parts binding due to installation or machining variations. With specifications including a maximum operating pressure of 5000 psi (350 bar), a flow capacity of up to 12 gpm (45 L/min), and rapid response times typically around 50 ms, this valve is suited for various demanding hydraulic applications requiring precise control and reliability.

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.
