The Sun Hydraulics DMDATRN71219 (DMDATRN71219) 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 rating of 5000 psi (350 bar), making it suitable for high-pressure applications. The valve offers closed transitions between positions B and R, enhancing performance by providing faster and more consistent response times especially in pilot control applications where capacity is less critical. This model operates without requiring a minimum hydraulic pressure, allowing for versatile use in various system configurations. Equipped with either D or L control options, it includes a manual override with a detent mechanism designed for temporary actuation, supporting up to approximately 7,000 cycles mechanically. The valve's EPDM seals are specifically intended for use with phosphate ester fluids; however, they are susceptible to damage when exposed to petroleum-based fluids. Additionally, the DMDATRN71219 utilizes a wet armature design which involves the working fluid surrounding the armature that may be affected by heat during prolonged coil energization. Its design also supports interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either orientation on the tube. The construction incorporates Sun\u2019s floating style to minimize internal part binding due to installation torque or machining variations of cavity/cartridge. Key specifications include a maximum flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, maximum operating pressure of 5000 psi (350 bar), and switching frequency up to 15000 cycles/hr. This model also features manual override requirements and detailed installation specifications including solenoid tube diameter and hex size for precise integration into 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.
