The Sun Hydraulics DMDAXPN72499 (DMDAXPN72499) is a solenoid-operated 3-way, 2-position cartridge valve that excels in precision fluid control within hydraulic systems. This direct-acting, balanced spool directional valve is designed to operate without minimum hydraulic pressure, making it highly effective for immediate system responses. The valve features a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 12 gpm (45 L/min), suitable for robust applications. The DMDAXPN72499 incorporates closed transitions between spool positions B and R, enhancing performance by ensuring faster and more consistent response times during operation. This feature is particularly beneficial when the valve is used as a pilot control where flow capacity is less critical. Additionally, the valve's solenoid tube assembly is fatigue rated for high-pressure service up to 5000 psi, ensuring durability and reliability under demanding conditions. This model also includes manual override options with detent mechanisms designed for temporary actuation, supporting a mechanical life expectancy of about 7,000 cycles. With interchangeable coils compatible with other Sun Series 1 solenoid products and a wet armature design, this valve maintains versatility across different setups and operational environments. However, it\u2019s important to note that the EPDM seals in this cartridge are specifically intended for systems using phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. Overall, the DMDAXPN72499 is engineered to provide reliable performance with minimal internal parts binding thanks to Sun\u2019s floating style construction which compensates for installation torque variations or cavity/cartridge machining discrepancies. This makes it an excellent choice for high-performance hydraulic systems requiring precise control and fast response times.

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.
