The Sun Hydraulics DMDADRN924N (DMDADRN924N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool directional design. This valve is specifically engineered to handle a maximum operating pressure of 5000 psi (350 bar) and offers a flow capacity of up to 12 gpm (45 L/min). It boasts a rapid response time of approximately 50 ms, making it suitable for applications requiring quick actuation. The construction of the DMDADRN924N includes a fatigue-rated solenoid tube assembly and incorporates Sun Hydraulics' floating style construction which minimizes internal parts binding. This feature ensures reliable performance even when variations in installation torque or cavity/cartridge machining occur. The valve's manual override, equipped with detent mechanism on models with D or L control, is designed for temporary actuation with an expected mechanical life of about 7,000 cycles. Designed for versatility in system integration, the DMDADRN924N's coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, this model uses EPDM seals recommended for systems utilizing phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they could cause damage. This valve's wet armature design allows the working fluid to surround the armature which helps manage heat during prolonged coil energization but requires consideration regarding fluid selection to prevent breakdown and varnish formation. Overall, the Sun Hydraulics DMDADRN924N offers robust performance and reliability for specialized hydraulic applications where precise control and fast response times are critical.

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.
