The Sun Hydraulics DMDADNV236 (DMDADNV236) is a high-performance solenoid-operated 3-way, 2-position cartridge valve, designed for direct-acting and balanced spool directional control. This model is particularly noted for its robust construction, featuring a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar) service. It offers superior performance by maintaining closed spools B and R during transitions between positions, which enhances response times and consistency when used as pilot controls. The DMDADNV236 operates without requiring a minimum hydraulic pressure, making it versatile for various applications. The manual override options available with this model include D, L, and T controls, each designed with a detent mechanism intended for temporary actuation and capable of enduring approximately 7,000 cycles. Another notable feature is the use of EPDM seals in cartridges configured for systems using phosphate ester fluids; however, these seals must avoid exposure to petroleum-based substances to prevent damage. This valve incorporates a wet armature design allowing the working fluid to surround the armature which could be significant if the coil remains energized over extended periods. The potential thermal impact on certain fluids like water-glycol mixtures is critical as it may lead to breakdown and varnish formation affecting cartridge functionality. Additionally, the interchangeable coils with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement. The construction integrates Sun's floating style design minimizing internal parts binding caused by excessive installation torque or machining variations of cavity/cartridge. With specifications including a flow capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), rapid response time typically around 50 ms, and switching frequency up to 15000 cycles per hour, the DMDADNV236 is equipped to handle demanding operational conditions efficiently while ensuring reliability and durability in industrial applications.
