The Sun Hydraulics DMDALNV4E24V (DMDALNV4E24V) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust operation with a fatigue rating of 5000 psi (350 bar). It features closed transitions between Spools B and R to enhance performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. The valve operates without requiring a minimum hydraulic pressure, making it versatile for various applications. It includes manual override options with the D or L control, which are intended for temporary actuation. The mechanical life expectancy of these manual controls is around 7,000 cycles. The valve's design incorporates EPDM seals suitable for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can degrade. A notable feature of the DMDALNV4E24V is its wet armature design that allows the working fluid to surround the armature, aiding in heat management during prolonged energization periods. This design consideration is crucial when using fluids like water-glycol mixtures that might degrade under high temperatures. Additionally, the valve's coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The construction adopts Sun's floating style to minimize internal parts binding due to installation torque or variations in cavity/cartridge machining. With a maximum operating pressure of 5000 psi and a flow capacity of up to 12 gpm (45 L/min), this valve ensures reliable performance across a range of industrial applications while maintaining tight control over leakage and 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.
