The Sun Hydraulics DMDALPN512 (DMDALPN512) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve operates without the need for minimum hydraulic pressure, enhancing its reliability and responsiveness across various applications. The valve features a fatigue rating of 5000 psi (350 bar), making it suitable for rigorous operations. Key specifications include a maximum flow capacity of 12 gpm (45 L/min) and a rapid typical response time of 50 ms. It supports a maximum operating pressure up to 5000 psi (350 bar), with maximum valve leakage at 110 SUS (24 cSt) maintained at 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). The valve's switching frequency can reach up to 15,000 cycles per hour, ensuring robust performance in demanding conditions. The DMDALPN512 incorporates Sun Hydraulics' floating style construction which minimizes internal parts binding due to variations in installation torque or cavity/cartridge machining. This model is equipped with EPDM seals suitable for systems using phosphate ester fluids; however, these seals are vulnerable to damage from exposure to petroleum-based fluids. For manual override operations, the model includes a detent mechanism designed for temporary actuation with an expected mechanical life of approximately 7,000 cycles. The manual override requires a force of about 5 lbs at 1000 psi (133 N at 100 bar) and has a stroke length of .10 inches (2.5 mm). Overall, the Sun Hydraulics DMDALPN512 offers precise control and reliable operation for specialized hydraulic applications where high pressure and rapid response are critical.

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.
