The Sun Hydraulics DMDAMBN724N (DMDAMBN724N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control in various applications. This direct-acting, balanced spool directional valve operates without a minimum hydraulic pressure requirement, making it versatile for use in different systems. It features a fatigue rating of 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. The spools B and R maintain a closed transition between their two positions, optimizing performance by providing faster and more consistent response times, particularly beneficial when used as pilot controls. The valve incorporates EPDM seals suitable for phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. With its wet armature design, the working fluid surrounds the armature which is critical to consider if the coil remains energized over extended periods due to potential breakdown of certain fluids like water-glycol mixtures. Additionally, the DMDAMBN724N features interchangeable coils with other Sun Series 1 solenoid products and supports a manual override mechanism designed primarily for temporary actuation with a mechanical life expectancy of about 7,000 cycles. The construction utilizes Sun's floating style to minimize internal part binding due to installation torque or cavity/cartridge machining variations. This model offers quick response times (typically around 50 ms), supports up to 12 gpm (45 L/min) flow capacity, and can handle up to 15000 switching cycles per hour. It also allows easy installation with its .75 in (19 mm) solenoid tube diameter and requires an installation torque between 30 - 35 lbf ft (41 - 47 Nm). The compact design weighs approximately .60 lb (0.30 kg), making it suitable for various setups requiring robust control within limited spaces.

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.
