The Sun Hydraulics DMDATNN71219 (DMDATNN71219) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for demanding hydraulic applications. It features a direct-acting, balanced spool directional control mechanism that ensures reliable operation without the need for minimum hydraulic pressure. This model is particularly noted for its fatigue rating of 5000 psi (350 bar), making it suitable for high-pressure environments. The valve's spool transitions are closed between the two positions, B and R, enhancing performance by providing faster and more consistent response times especially when used as pilot controls. The DMDATNN71219 incorporates a wet armature design where the working fluid surrounds the armature, crucial in applications where the coil may be energized for extended periods. This design consideration helps mitigate potential thermal degradation of hydraulic fluids. For environments utilizing phosphate ester fluids, cartridges with EPDM seals are recommended to prevent damage from petroleum-based substances. The manual override feature in models equipped with D or L control is intended for temporary actuation and boasts a mechanical life expectancy of around 7,000 cycles. Other notable features include interchangeable coils compatible with other Sun Series 1 solenoid products, Sun's floating style construction to minimize internal binding due to installation variances, and a robust switching frequency of up to 15,000 cycles per hour. The valve also supports a maximum flow capacity of 12 gpm (45 L/min) and exhibits minimal leakage even under maximum operating pressure conditions. Overall, the Sun Hydraulics DMDATNN71219 valve is engineered for precision and durability in complex hydraulic systems where performance and reliability 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.
