The Sun Hydraulics DMDAMRN72419 (DMDAMRN72419) is a high-performance solenoid-operated 3-way, 2-position cartridge valve, designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve features a fatigue rating of 5000 psi (350 bar), making it suitable for high-pressure operations. The solenoid tube assembly enhances the valve's durability and performance under continuous use. Key to its functionality, the DMDAMRN72419 incorporates closed transitions between Spools B and R, optimizing performance by ensuring faster and more consistent response times during operation. This feature is particularly beneficial in pilot control applications where capacity is less critical compared to response accuracy and speed. Additionally, the valve operates without requiring a minimum hydraulic pressure, providing versatility across various hydraulic systems. The model is equipped with manual override options (D or L control), which include a detent mechanism intended for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. For environments utilizing phosphate ester fluids, cartridges configured with EPDM seals are recommended to avoid damage from petroleum-based substances. This valve also employs a wet armature design where the working fluid surrounds the armature; this design consideration is crucial when the coil remains energized for extended periods as it impacts fluid integrity due to heat exposure. Furthermore, its compatibility with other Sun Series 1 solenoid products allows for flexible interchangeability of coils which can be mounted in either direction on the tube. Incorporating Sun\u2019s floating style construction minimizes internal parts binding that could result from excessive installation torque or machining variations of cavity/cartridge. With a maximum flow capacity of 12 gpm (45 L/min) and rapid response times typically around 50 ms, the Sun Hydraulics DMDAMRN72419 provides reliable and efficient directional control in demanding hydraulic applications.

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.
