The Sun Hydraulics DMDAXNV72499 (DMDAXNV72499) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve ensures efficient control with its capability to handle a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min). The DMDAXNV72499 features a unique closed transition between Spools B and R, optimizing performance by providing faster and more consistent response times especially beneficial in pilot control scenarios where capacity is less critical. This model is engineered with durability in mind, incorporating a fatigue-rated solenoid tube assembly suitable for high-pressure service. It includes an optional manual override mechanism equipped with a detent feature intended for temporary actuation, boasting a mechanical life expectancy of around 7,000 cycles. The valve's construction utilizes EPDM seals specifically designed for compatibility with phosphate ester fluids, while avoiding exposure to petroleum-based substances which could compromise seal integrity. Additionally, the DMDAXNV72499 benefits from Sun Hydraulics\u2019 floating style construction which minimizes internal part binding due to installation variances or cavity/cartridge machining discrepancies. Its wet armature design allows the working fluid to cool the armature, although care must be taken as certain fluids can degrade under prolonged heat exposure. For versatile application across various setups, this model\u2019s coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either orientation on the tube. This valve is an essential component for systems requiring reliable and precise fluid control in demanding operational 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.
