The Sun Hydraulics DMDATNV924 (DMDATNV924) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust and efficient control in hydraulic systems. It features a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar), making it suitable for demanding applications. The valve's spools B and R are closed during the transition between positions, enhancing performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. The DMDATNV924 operates without requiring a minimum hydraulic pressure, adding to its versatility in various system configurations. It includes options for manual override with detent mechanisms intended for temporary actuation, supporting mechanical life expectancies around 7,000 cycles. The valve uses EPDM seals specifically designed for systems utilizing phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based substances. Additionally, the valve employs a wet armature design wherein the working fluid surrounds the armature which may be a consideration during extended periods of coil energization due to potential breakdowns in certain fluid types like water-glycol mixtures. Interchangeability of coils with other Sun Series 1 solenoid products offers flexibility in maintenance and upgrades. The construction incorporates Sun\u2019s floating style design which minimizes internal parts binding caused by installation or machining discrepancies. With specifications including a flow capacity of 12 gpm (45 L/min), rapid typical response times of 50 ms, and maximum operating pressures up to 5000 psi (350 bar), this valve is engineered to meet rigorous industrial demands while maintaining precise control and reliability in hydraulic operations.

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.
