The Sun Hydraulics DMDATBN724 (DMDATBN724) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precision hydraulic control. This direct-acting, balanced spool directional valve is characterized by its robust design, including a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar) service. The valve features closed transitions between Spools B and R, optimizing performance by ensuring faster and more consistent response times particularly useful in pilot control applications where capacity is less critical. The DMDATBN724 operates without requiring a minimum hydraulic pressure, enhancing its versatility in various system configurations. For manual override operations, the valve includes a detent mechanism designed for temporary actuation with a mechanical life expectancy of about 7,000 cycles. It is essential to note that cartridges with EPDM seals are specifically intended for systems using phosphate ester fluids; exposure to petroleum-based fluids will compromise the seal integrity. Additionally, the wet armature design of this model means the coil\u2019s heat will interact directly with the hydraulic fluid which could influence fluid integrity over extended periods of energization. The valve's compatibility with other Sun Series 1 solenoid products allows for interchangeable coils that can be mounted in either direction on the tube. This model also incorporates Sun's floating style construction to reduce internal parts binding due to installation torque or machining variations. Key specifications include a maximum flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum operating pressure of 5000 psi (350 bar). The valve's switching frequency can reach up to 15,000 cycles per hour, ensuring reliable performance under demanding conditions.

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.
