The Sun Hydraulics DMDALBV71219 (DMDALBV71219) 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 is notable for its fatigue rating at 5000 psi (350 bar), making it suitable for high-pressure environments. The valve features closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times during operation\u2014ideal when used as pilot controls where capacity is less critical. The DMDALBV71219 operates without requiring a minimum hydraulic pressure, facilitating its use in various hydraulic systems without the need for additional pressure support. It includes manual override options with a detent mechanism designed for temporary actuation, and the manual control assembly boasts a mechanical life expectancy of approximately 7,000 cycles. The valve's cartridges are compatible with EPDM seals intended specifically for systems using phosphate ester fluids; however, these seals must avoid contact with petroleum-based fluids to prevent damage. Additionally, this model incorporates a wet armature design where the working fluid surrounds the armature which might be susceptible to heat during prolonged coil energization\u2014important to consider in system design to avoid fluid breakdown. The interchangeable coils with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement. The construction of the DMDALBV71219 minimizes internal parts binding through its floating style construction\u2014a feature that addresses installation torque and machining variations that could otherwise impact performance. Key specifications include a flow capacity of up to 12 gpm (45 L/min), swift response times typically around 50 ms, and maximum operating pressures up to 5000 psi (350 bar). This model also supports frequent switching applications with its capability of handling up to 15,000 cycles per hour, making it an excellent choice for dynamic systems requiring reliable directional control.
