The Sun Hydraulics DMDAXRV828 (DMDAXRV828) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. Featuring a direct-acting, balanced spool design, this model ensures reliable operation without the need for minimum hydraulic pressure. The valve operates with a maximum pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min), making it suitable for various demanding applications. The DMDAXRV828 incorporates advanced features such as closed transitions between spool positions B and R, enhancing performance by providing faster and more consistent response times crucial in pilot control applications. Its wet armature design allows the working fluid to surround the armature which helps in heat dissipation but requires consideration of fluid type due to potential breakdowns at high temperatures. This model is equipped with EPDM seals specifically for use with phosphate ester fluids; however, it is sensitive to exposure to petroleum-based fluids which can damage the seals. The manual override feature included in models with D or L control uses a detent mechanism designed for temporary actuation with an expected mechanical life of around 7,000 cycles. Additionally, the DMDAXRV828 benefits from interchangeable coils compatible with other Sun Series 1 solenoid products and features Sun\u2019s floating style construction that minimizes internal parts binding. This robust construction coupled with its technical specifications makes the DMDAXRV828 an excellent choice for applications requiring precise directional control and reliability under high-pressure conditions.
