The Sun Hydraulics DMDALRV628 (DMDALRV628) 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 is engineered to handle a maximum operating pressure of 5000 psi (350 bar) and offers a flow capacity of up to 12 gpm (45 L/min). Its design includes spools B and R which are closed during the transition between positions, enhancing performance by ensuring faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. The DMDALRV628 features a wet armature design, meaning the armature is immersed in the hydraulic fluid, which helps in cooling but requires attention regarding fluid selection as certain fluids can degrade under prolonged exposure to heat. It is compatible with EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage from petroleum-based fluids. This model also supports interchangeable coils from other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The manual override mechanism included in this valve is designed for temporary actuation with a mechanical life expectancy of about 7,000 cycles. Additionally, it incorporates Sun's floating style construction which minimizes internal parts binding due to installation torque or machining variations. With a typical response time of 50 ms and switching frequency capabilities up to 15,000 cycles per hour, the DMDALRV628 ensures reliable and efficient operation in demanding hydraulic setups. The valve also features manual override options requiring minimal force and provides precise control with its .10 inch (2.5 mm) stroke capability. This compact yet sturdy model weighs approximately .60 lb (0.30 kg), making it an excellent choice for integrated hydraulic systems requiring high reliability and performance.
