The Sun Hydraulics DMDADPV224 (DMDADPV224) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve operates without the need for a minimum hydraulic pressure, making it highly effective in a variety of operational contexts. The valve features a fatigue rating of 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. Notably, the DMDADPV224 employs a wet armature design where the working fluid surrounds the armature. This design is crucial in managing the heat generated by the coil, which can be particularly beneficial when using water-glycol mixtures that are prone to breakdown and varnish formation at high temperatures. The spools B and R maintain a closed transition between positions, optimizing performance by providing faster and more consistent response times at the expense of lower capacity\u2014ideal for pilot control applications where capacity is less critical. Additionally, this model incorporates interchangeable coils with other Sun Series 1 solenoid products and features Sun's floating style construction to minimize internal parts binding due to installation torque or machining variations of cavity/cartridge. The manual override mechanism included on models with D or L control is designed for temporary actuation with an expected mechanical life of about 7,000 cycles. The DMDADPV224 also boasts impressive specifications such as a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and rapid response times typically around 50 ms. It is configured to support EPDM seals suitable for phosphate ester fluids but should avoid exposure to petroleum-based fluids which could damage the seals.
