The Sun Hydraulics DMDALRV614 (DMDALRV614) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This model features a robust solenoid tube assembly rated for fatigue at 5000 psi (350 bar), making it suitable for demanding applications. The valve's spools, B and R, maintain a closed position during transitions between two states, enhancing performance by ensuring faster and more consistent response times especially when used as pilot controls. This valve operates without the need for minimum hydraulic pressure, facilitating reliable performance across various operational conditions. The manual override in models with D or L control is intended for temporary actuation and the mechanism has a mechanical life expectancy of around 7,000 cycles. For environments utilizing phosphate ester fluids, cartridges with EPDM seals are recommended to prevent damage from petroleum-based substances. The design incorporates a wet armature setup where the working fluid envelops the armature; this is crucial as prolonged energization can heat the fluid affecting its performance over time. It\u2019s important to note that water-glycol mixtures may degrade under such conditions. Additionally, the interchangeable coils compatible with other Sun Series 1 products offer flexibility in mounting direction. To ensure durability and minimize internal binding risks due to installation torque or machining variations of cavity/cartridge, this model employs Sun\u2019s floating style construction. Key specifications include a flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum operating pressure of 5000 psi (350 bar). The manual override requires minimal force and has a short stroke length for efficient operation. This compact unit weighs about 0.60 lb (0.30 kg) and adheres to stringent leakage standards ensuring reliability in high-demand settings.
