The Sun Hydraulics DMDADRV71219 (DMDADRV71219) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust and precise hydraulic control. This direct-acting, balanced spool directional valve ensures reliable operation with its fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar). The valve features closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, especially suitable for applications where capacity is not a critical factor. The DMDADRV71219 requires no minimum hydraulic pressure for operation, making it highly versatile in various hydraulic systems. It includes manual override options with a detent mechanism designed for temporary actuation and boasts a mechanical life expectancy of approximately 7,000 cycles. Notably, this model incorporates EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. Additionally, the valve's wet armature design allows the working fluid to surround the armature which may affect the fluid's integrity if the coil remains energized for extended periods. Interchangeability of coils with other Sun Series 1 solenoid products adds flexibility in maintenance and replacement procedures. The construction employs Sun's floating style design minimizing internal binding risks due to installation torque or cavity/cartridge machining variations. With a maximum flow capacity of 12 gpm (45 L/min) and rapid response time typically around 50 ms, this valve is ideal for applications requiring precise control over fluid direction and flow. Its robust build and interchangeable components make it a reliable choice for 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.
