The Sun Hydraulics DMDAXPN524 (DMDAXPN524) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve operates with a maximum capacity of 12 gpm (45 L/min) and can handle up to 5000 psi (350 bar). The valve features a rapid response time of approximately 50 ms and is engineered to ensure low leakage with a maximum rate of 5 in\u00b3/min at 3000 psi. Its robust design includes interchangeable coils from the Sun Series 1 solenoid products, which can be mounted in either direction for increased flexibility in system design. This model is particularly noted for its closed transition between spools B and R, enhancing performance by ensuring faster and more consistent response times, ideal for applications requiring precise control such as pilot operations where flow capacity is less critical. The DMDAXPN524 also incorporates Sun's floating style construction which minimizes internal parts binding due to installation torque or machining variations of the cavity/cartridge. For environments using phosphate ester fluids, cartridges configured with EPDM seals are recommended, while exposure to petroleum-based fluids should be avoided to prevent seal damage. Additionally, the manual override feature included in models equipped with D or L control is designed for temporary actuation only, with a mechanical life expectancy of about 7,000 cycles. This valve's wet armature design allows the working fluid to surround the armature, which could be relevant when considering fluid types that degrade at higher temperatures due to prolonged coil energization. Installation specifics include a solenoid tube diameter of .75 inches and a valve hex size of 7/8 inches. The recommended installation torque is between 30-35 lbf-ft to ensure optimal performance and durability.

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.
