The Sun Hydraulics DMDALBV914 (DMDALBV914) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust and efficient hydraulic system control. This direct-acting, balanced spool directional valve is constructed to handle a maximum operating pressure of 5000 psi (350 bar) and is fatigue rated for demanding applications. It features closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, especially suitable for pilot controls where capacity is less critical. The DMDALBV914 operates without requiring a minimum hydraulic pressure, thereby ensuring reliable functionality in various system conditions. Models equipped with the D or L control include a detent mechanism in the manual override intended for temporary actuation, with a mechanical life expectancy of approximately 7,000 cycles. The valve also incorporates EPDM seals specifically for use with phosphate ester fluids; however, these seals must avoid exposure to petroleum-based fluids to prevent damage. Additionally, this model uses a wet armature design where the working fluid surrounds the armature. This design consideration is crucial as prolonged coil energization can lead to fluid degradation at high temperatures. The interchangeable coils with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement. The valve also benefits from Sun\u2019s floating style construction which minimizes internal parts binding due to installation torque or machining variations of cavity/cartridge. With a flow capacity of up to 12 gpm (45 L/min), quick typical response times of around 50 ms, and minimal maximum valve leakage at high pressures, the DMDALBV914 is an effective solution for directing flow in hydraulic systems efficiently and reliably.
