The Sun Hydraulics DMDALRV71219 (DMDALRV71219) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve features a fatigue rating for up to 5000 psi (350 bar) service, making it suitable for demanding applications. The valve operates with no minimum hydraulic pressure required, ensuring reliable functionality under varying conditions. The DMDALRV71219 incorporates closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times when used as pilot controls. This feature is particularly beneficial in applications where capacity is less critical but speed and precision are paramount. Additionally, the valve's manual override mechanism is designed for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. Equipped with EPDM seals, the DMDALRV71219 is intended for use in systems utilizing phosphate ester fluids; however, it should not be exposed to petroleum-based fluids which can damage the seals. The wet armature design of the valve allows the working fluid to surround the armature, which could be a consideration if the coil remains energized over extended periods potentially leading to fluid degradation. This model also benefits from Sun Hydraulics' floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. With interchangeable coils that are compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube, this valve offers flexible installation options. The DMDALRV71219 supports up to 12 gpm (45 L/min) capacity and includes features like a maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and a switching frequency of up to 15,000 cycles per hour.

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.
