The Sun Hydraulics DMDAMBV71219 (DMDAMBV71219) is a high-performance solenoid-operated 3-way, 2-position cartridge valve, designed for direct-acting and balanced spool directional control. With a robust construction that features a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service, this valve is engineered for reliability and durability under demanding conditions. The model incorporates closed transitions between spool positions B and R, enhancing performance by ensuring faster and more consistent response times, especially suitable for applications where rapid actuation is critical. This valve operates without the need for a minimum hydraulic pressure, making it versatile across various hydraulic systems. It is equipped with manual overrides in some models (D or L control), which are intended for temporary actuation with a mechanical life expectancy of around 7,000 cycles. The EPDM seals configured cartridges are specifically designed for use with phosphate ester fluids, avoiding damage from petroleum-based substances. The DMDAMBV71219 utilizes a wet armature design which allows the working fluid to surround the armature\u2014this aids in managing the heat generated by the coil but requires consideration regarding fluid stability under prolonged energization. Its compatibility with other Sun Series 1 solenoid products offers flexibility in system design through interchangeable coils that can be mounted in either direction on the tube. Additionally, this model benefits from Sun's floating style construction which minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With specifications including a maximum flow capacity of 12 gpm (45 L/min), rapid typical response time of 50 ms, and stringent leakage control measures, the Sun Hydraulics DMDAMBV71219 valve is an effective solution tailored for precise fluid power management in advanced 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.
