The Sun Hydraulics DMDALAN828 (DMDALAN828) is a high-performance solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool directional control mechanism. This valve is specifically designed for robust applications, boasting a fatigue rating for 5000 psi (350 bar) service, making it suitable for high-pressure environments. Its spool transitions between positions B and R are closed, enhancing performance limits but with lower capacity, which is ideal for pilot controls where capacity is less critical but fast and consistent response times are necessary. The DMDALAN828 operates without requiring a minimum hydraulic pressure, adding to its versatility in various system configurations. It includes options for manual overrides with the D or L control featuring a detent mechanism intended for temporary actuation. The mechanical life expectancy of these manual control assemblies reaches approximately 7,000 cycles. Notably, this model employs EPDM seals suitable for systems using phosphate ester fluids; however, these seals must avoid exposure to petroleum-based substances to prevent damage. A distinctive feature of the DMDALAN828 is its wet armature design; the working fluid surrounds the armature which might be subjected to heat from prolonged coil energization \u2013 an aspect crucial in thermal management considerations. The valve\u2019s coils are interchangeable with other Sun Series 1 solenoid products and can be oriented in either direction upon mounting. Furthermore, this valve incorporates Sun's innovative floating style construction which minimizes potential internal binding due to excessive installation torque or variations in cavity/cartridge machining. With capabilities like a flow capacity of up to 12 gpm (45 L/min) and rapid typical response times of 50 ms, alongside a maximum operating pressure of 5000 psi (350 bar), the DMDALAN828 stands out as a reliable component for advanced hydraulic systems requiring precise control and durability.
