The Sun Hydraulics DMDADBV72419 (DMDADBV72419) is a highly efficient, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust performance in various hydraulic systems. It features a fatigue rating of 5000 psi (350 bar), making it suitable for high-pressure applications. The unique construction of the spool ensures that ports B and R are closed during the transition between positions, enhancing performance by providing faster and more consistent response times especially useful in pilot control applications where capacity is less critical. The valve operates without the need for a minimum hydraulic pressure, allowing for versatile use across different hydraulic setups. It includes options for manual control with detent mechanisms designated for temporary actuation, ensuring durability with an estimated mechanical life of approximately 7,000 cycles. The DMDADBV72419 is equipped with EPDM seals specifically for use with phosphate ester fluids; however, these seals must avoid contact with petroleum-based substances to prevent damage. Additionally, this model employs a wet armature design where the working fluid surrounds the armature which could be subject to heat during prolonged energization\u2014important to consider when using certain fluid types that may degrade under heat. The valve's compatibility with interchangeable coils from other Sun Series 1 solenoid products adds to its flexibility in system design. It also incorporates Sun\u2019s floating style construction which minimizes internal parts binding due to installation variances. With specifications like a maximum flow capacity of 12 gpm (45 L/min), rapid response time typically around 50 ms, and very low maximum valve leakage at high pressures, the DMDADBV72419 stands out as a reliable choice for efficient directional control in hydraulic systems.
