The Sun Hydraulics DMDALNV224N (DMDALNV224N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for demanding hydraulic applications. This direct-acting, balanced spool directional valve ensures robust operation with its fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service. The valve features closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, especially suitable when used as pilot controls. The DMDALNV224N operates without requiring a minimum hydraulic pressure, making it versatile for various hydraulic systems. It includes manual override options with a detent mechanism designed for temporary actuation, supporting up to approximately 7,000 cycles. The valve is equipped with EPDM seals specifically for use with phosphate ester fluids; however, these seals must avoid exposure to petroleum-based fluids to prevent damage. A notable feature of this model is its wet armature design where the working fluid surrounds the armature\u2014important to consider as prolonged energization of the coil can lead to fluid breakdown in certain conditions. Additionally, the valve\u2019s coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. With a capacity of up to 12 gpm (45 L/min) and maximum operating pressure of 5000 psi (350 bar), along with a typical response time of 50 ms and switching frequency up to 15,000 cycles/hr, this valve is engineered for high efficiency and reliability in hydraulic control systems. It also incorporates Sun's floating style construction which minimizes internal part binding due to installation torque or machining variations in cavity/cartridge setups.

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.
