The Sun Hydraulics DMDALBN4E24V (DMDALBN4E24V) is a high-performance solenoid-operated 3-way, 2-position cartridge valve, specifically designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve ensures reliable control with its fatigue-rated solenoid tube assembly capable of handling services up to 5000 psi (350 bar). The valve features closed transitions between Spools B and R, optimizing performance by offering faster and more consistent response times particularly suitable for pilot controls where capacity is less critical. Engineered for versatility, the DMDALBN4E24V operates without requiring a minimum hydraulic pressure, making it ideal for a wide range of operational environments. It includes options such as manual overrides with a detent mechanism intended for temporary actuation, which has a mechanical life expectancy of about 7,000 cycles. The model can be equipped with EPDM seals for compatibility with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. Additionally, the valve's wet armature design allows the working fluid to surround the armature which helps in heat management but requires consideration of fluid characteristics as some may degrade under prolonged heat exposure. The interchangeable coils compatible with other Sun Series 1 solenoid products add to the flexibility and ease of use by allowing mounting on the tube in either direction. Furthermore, this model incorporates Sun's floating style construction which minimizes internal parts binding resulting from excessive installation torque or variations in cavity/cartridge machining. With specifications including a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and typical response time of 50 ms, this valve is an efficient solution tailored for demanding hydraulic applications requiring precise control and 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.
