The Sun Hydraulics DMDALPV4E12V (DMDALPV4E12V) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve operates without requiring a minimum hydraulic pressure, making it versatile for various applications. It features a robust design with the solenoid tube assembly rated for fatigue at 5000 psi (350 bar), ensuring durability and reliability in demanding environments. This model's valve operation is characterized by closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times, especially suitable for pilot control applications where capacity is less critical. The manual override in models with D or L control includes a detent mechanism intended for temporary actuation, with a mechanical life expectancy of about 7,000 cycles. For compatibility with different hydraulic fluids, cartridges configured with EPDM seals are specifically designed for systems using phosphate ester fluids; however, they must avoid exposure to petroleum-based fluids to prevent seal damage. The valve's wet armature design allows the working fluid to surround the armature which can be significant if the coil remains energized over extended periods as some fluids may degrade under heat. Additionally, this model incorporates Sun\u2019s floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. With interchangeable coils within the Sun Series 1 solenoid products and a capacity of 12 gpm (45 L/min), this valve offers flexibility and ease of use in various hydraulic setups. Other technical specifications include a maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum valve leakage at 110 SUS (24 cSt) being minimal at 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). This makes the DMDALPV4E12V an ideal choice for sophisticated hydraulic systems requiring reliable directional control and rapid response times.

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.
