The Sun Hydraulics DMDADRN72499 (DMDADRN72499) 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 operates with no minimum hydraulic pressure required, ensuring reliable control across a variety of operations. The valve features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), making it suitable for high-pressure environments. Equipped with interchangeable coils compatible with other Sun Series 1 solenoid products, the DMDADRN72499 offers flexible installation options as the coils can be mounted in either direction on the tube. This valve also incorporates Sun\u2019s floating style construction which minimizes internal parts binding and potential damage from excessive installation torque or cavity/cartridge machining variations. The manual override feature in models with the D or L control is designed for temporary actuation and has a mechanical life expectancy of about 7,000 cycles. Additionally, the wet armature design of this valve means that the working fluid surrounds the armature which could be a consideration if exposed to prolonged energization periods. For systems utilizing phosphate ester fluids, cartridges configured with EPDM seals are recommended as exposure to petroleum-based fluids can damage these seals. With a maximum flow capacity of 12 gpm (45 L/min) and quick response times typically around 50 ms, this valve ensures efficient operation and control precision in your hydraulic systems. The manual override requires minimal force and has a short stroke distance for easy operation under pressure 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.
