The Sun Hydraulics DMDALPN4E24V (DMDALPN4E24V) is a high-performance solenoid-operated 3-way, 2-position cartridge valve that features direct-acting, balanced spool directional control. This valve is designed to operate without minimum hydraulic pressure, making it versatile for various applications. The unique construction includes a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. The DMDALPN4E24V offers precise control with closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. This model incorporates manual override options with a detent mechanism intended for temporary actuation, supporting a mechanical life expectancy of about 7,000 cycles. Equipped to handle EPDM seals, the DMDALPN4E24V is compatible with systems using phosphate ester fluids. However, it is sensitive to exposure to petroleum-based fluids which can damage the seals. The valve's wet armature design allows the working fluid to surround the armature which could be susceptible to heat during prolonged energization, potentially affecting fluid integrity over time. This model also features interchangeable coils with other Sun Series 1 solenoid products and supports a floating style construction that minimizes internal parts binding due to installation variances or machining discrepancies. With specifications like a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and rapid response times typically around 50 ms, the DMDALPN4E24V is an efficient solution for demanding directional control applications requiring robust performance and high reliability.

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.
