The Sun Hydraulics DMDALNV924 (DMDALNV924) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve features a robust design with a solenoid tube assembly that is fatigue rated for 5000 psi (350 bar) service, ensuring reliable operation under high-pressure conditions. The valve's spools, B and R, are closed during the transition between positions which enhances performance by providing faster and more consistent response times especially suited for applications as pilot controls where capacity is less critical. This model is equipped with manual override options D or L control, where the detent mechanism allows for temporary actuation; the mechanical life expectancy of this manual control assembly is about 7,000 cycles. Notably, cartridges configured with EPDM seals are specifically designed for use with phosphate ester fluids; however, they must not be exposed to petroleum-based fluids as these will damage the seals. The DMDALNV924 utilizes a wet armature design allowing the working fluid to surround the armature which could be a consideration if the coil remains energized for extended periods. This valve also features interchangeable coils that are compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, it incorporates Sun\u2019s floating style construction to minimize internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. With specifications including a maximum flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum operating pressure of 5000 psi (350 bar), this valve is engineered to meet rigorous industrial demands while ensuring precise fluid control in hydraulic systems.

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.
