The Sun Hydraulics DMDAMRN214 (DMDAMRN214) is a solenoid-operated 3-way, 2-position cartridge valve that functions as a direct-acting, balanced spool directional valve. Designed for robust performance, this model features a solenoid tube assembly rated for fatigue at 5000 psi (350 bar), making it suitable for high-pressure applications. The valve incorporates closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times, particularly when used as pilot controls where flow capacity is less critical. This direct-actuated valve operates without the need for minimum hydraulic pressure, offering versatility in various hydraulic systems. It includes options for manual override through the D or L control, which are intended for temporary actuation with a mechanical life expectancy of around 7,000 cycles. For environments using phosphate ester fluids, cartridges with EPDM seals are available; however, these seals are not compatible with petroleum-based fluids as they can cause damage. The DMDAMRN214 employs a wet armature design whereby the working fluid surrounds the armature. This design consideration is crucial when the coil is energized for extended periods since some fluids may degrade under prolonged exposure to heat. The interchangeable coils with other Sun Series 1 solenoid products add to the flexibility of this model. Additionally, it features Sun\u2019s floating style construction which minimizes internal parts binding due to installation torque or machining variations of cavity/cartridge. With specifications that include a maximum operating pressure of 5000 psi (350 bar), capacity up to 12 gpm (45 L/min), and typical response times of 50 ms, this valve supports high-frequency switching up to 15,000 cycles/hr. It is engineered to meet demanding hydraulic system requirements while ensuring reliability and performance consistency.
