The Sun Hydraulics DMDALRN614 (DMDALRN614) is a solenoid-operated, 3-way, 2-position cartridge valve that exemplifies precision and durability in fluid power management. This direct-acting, balanced spool directional valve is specifically designed to handle a maximum operating pressure of 5000 psi (350 bar), making it suitable for high-pressure applications. The DMDALRN614 features a unique closed transition between Spools B and R, enhancing performance by ensuring faster and more consistent response times during operation. This model is particularly noted for its robust solenoid tube assembly which is fatigue rated for demanding 5000 psi service conditions. It operates without requiring a minimum hydraulic pressure, allowing for versatile use in various hydraulic systems. Additionally, the valve incorporates EPDM seals suitable for phosphate ester fluids, although these seals must be protected from exposure to petroleum-based substances which can cause damage. Another significant aspect of the DMDALRN614 is its wet armature design. This design involves the working fluid surrounding the armature, which helps manage the heat generated by the coil but requires consideration of fluid characteristics as some may degrade under prolonged exposure to heat. For ease of maintenance and compatibility, the coils of this valve are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The manual override feature included in models with D or L control uses a detent mechanism designed primarily for temporary actuation with an expected mechanical life of around 7,000 cycles. The DMDALRN614 also benefits from Sun's floating style construction which minimizes internal part binding due to installation torque or machining variations in cavity-cartridge setups. With a typical response time of 50 ms and capable of handling up to 12 gpm (45 L/min), this valve ensures efficient flow control in critical applications.
