The Sun Hydraulics DMDALPV223 (DMDALPV223) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve is engineered to handle a maximum operating pressure of 5000 psi (350 bar) and features a robust design with a fatigue rating that matches its high-pressure capability. The valve's spools, B and R, remain closed during the transition between positions to ensure high performance with lower capacity, which is ideal when used as pilot controls where speed and consistency are crucial. The DMDALPV223 operates without requiring a minimum hydraulic pressure, making it versatile for various applications. It includes manual override options with the D or L control featuring a detent mechanism designed for temporary actuation. The mechanical life expectancy of this manual control assembly reaches approximately 7,000 cycles. Another notable feature is its compatibility with EPDM seals suited for systems using phosphate ester fluids; however, these seals must avoid exposure to petroleum-based substances to prevent damage. This model also incorporates a wet armature design where the working fluid surrounds the armature. This design consideration is essential as it can influence the fluid's stability if the coil remains energized for extended periods. Additionally, the interchangeable coils with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement. The valve's construction benefits from Sun\u2019s floating style design which minimizes internal part binding due to installation torque or cavity/cartridge machining variations. With specifications including a flow capacity of up to 12 gpm (45 L/min) and typical response times of 50 ms, along with features like a maximum switching frequency of 15,000 cycles/hr and very low leakage rates at high pressures, the DMDALPV223 is well-suited for demanding applications requiring reliable and efficient directional control in hydraulic systems.
