The Sun Hydraulics DMDALPV224N (DMDALPV224N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve is optimized for use in environments requiring precise control and reliability. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 12 gpm (45 L/min), it is well-suited for demanding industrial applications. The DMDALPV224N features closed transitions between positions B and R, enhancing performance by ensuring faster and more consistent response times, particularly beneficial in pilot control setups where capacity is less critical. Its wet armature design allows the working fluid to surround the armature, which can be a consideration when the coil is energized for extended periods as certain fluids may degrade under prolonged exposure to heat. This valve requires no minimum hydraulic pressure to operate and includes interchangeable coils that are compatible with other Sun Series 1 solenoid products. The manual override option, equipped with a detent mechanism, supports temporary actuation and has a mechanical life expectancy of approximately 7,000 cycles. Additionally, the valve incorporates Sun's floating style construction which minimizes internal part binding due to installation torque or cavity/cartridge machining variations. Designed for durability and efficient operation across various hydraulic systems, the DMDALPV224N also features EPDM seals suitable for phosphate ester fluids while being incompatible with petroleum-based fluids which could damage the seals. This versatility makes it an essential component for specialized hydraulic circuits looking for reliable directional control.

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.
