The Sun Hydraulics DMDAMRV528 (DMDAMRV528) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for various hydraulic applications. It features a direct-acting, balanced spool directional control mechanism that operates without requiring a minimum hydraulic pressure, enhancing its versatility in different system conditions. The valve is specifically engineered to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min), making it suitable for robust hydraulic tasks. This model is equipped with a fatigue-rated solenoid tube assembly, ensuring durability and reliability even under high-pressure cycles. The transition between the spool positions B and R is closed, which although limits capacity, significantly enhances performance by providing faster and more consistent response times\u2014typically around 50 ms. Such features make the DMDAMRV528 ideal for pilot control applications where swift actuation is crucial. Additionally, the DMDAMRV528 incorporates EPDM seals suited for phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. The wet armature design of the valve helps in cooling but requires consideration regarding the type of fluid used due to potential breakdown at high temperatures. 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 about 7,000 cycles. For ease of maintenance and adaptability, coils in this model are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Sun Hydraulics has also designed this valve with their floating style construction to minimize internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. This thoughtful engineering ensures reliable operation and longevity of the valve even in demanding installations.
