The Sun Hydraulics DMDALRN914 (DMDALRN914) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precision control in hydraulic systems. This direct-acting and balanced spool directional valve is notable for its robust construction and compatibility with high-pressure applications up to 5000 psi (350 bar). The DMDALRN914 features a unique closed transition between spools B and R, enhancing performance by providing faster and more consistent response times, especially suitable for pilot control operations where capacity is less critical. Engineered with a wet armature design, the DMDALRN914's working fluid surrounds the armature which is beneficial for heat dissipation but requires careful consideration of fluid type to avoid breakdown and varnish formation, particularly with water-glycol mixtures. The valve's manual override options come equipped with a detent mechanism intended for temporary actuation, supporting mechanical life expectancy around 7,000 cycles. Furthermore, the unit incorporates Sun\u2019s floating style construction which minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. It also offers interchangeable coils with other Sun Series 1 solenoid products, enhancing versatility and ease of maintenance. This model specifically uses EPDM seals suitable for phosphate ester fluids while being incompatible with petroleum-based fluids that could damage the seals. With a capacity of 12 gpm (45 L/min) and typical response time of 50 ms, along with maximum valve leakage at 110 SUS (24 cSt) being limited to 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar), the DMDALRN914 is engineered to meet rigorous industrial demands while ensuring reliability and efficiency in operation.

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.
