The Sun Hydraulics DMDADNV524 (DMDADNV524) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control. This direct-acting, balanced spool directional valve is particularly noted for its robust construction 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, enhancing performance by ensuring faster and more consistent response times, ideal for applications where capacity is less critical but speed and reliability are paramount. With no minimum hydraulic pressure required for operation, the DMDADNV524 offers versatile deployment in various hydraulic systems. It includes options such as manual overrides with a detent mechanism that supports temporary actuation; these overrides are designed to withstand approximately 7,000 cycles. The valve\u2019s wet armature design means the working fluid surrounds the armature which could impact fluid integrity under prolonged coil energization. Configurations with EPDM seals are tailored for use with phosphate ester fluids; however, these seals must avoid contact with petroleum-based substances to prevent damage. Additionally, the interchangeable coils compatible with other Sun Series 1 solenoid products add to the flexibility of this model. Its floating style construction minimizes risks related to internal parts binding caused by installation issues or cavity/cartridge machining variations. Key specifications include a maximum flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum operating pressures sustained at 5000 psi (350 bar). This model also supports switching frequencies up to 15,000 cycles/hr and has manual override features that require minimal force. All these attributes make the DMDADNV524 an excellent choice for sophisticated hydraulic systems requiring reliable directional control and rapid response functionalities.

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.
