The Sun Hydraulics DMDMLRN (DMDMLRN) is a manually operated, 2-position, 3-way directional cartridge valve designed for hydraulic circuit flow direction control. It features a direct-acting, balanced spool valve mechanism that is specifically intended for intermittent use only, particularly as a manual override. This model incorporates Sun's TwistLock manual override mechanism which provides different operational modes: momentary-twist control (option T), detent-lock control (option L), and dual-operation control (option D). Each mode offers specific functionality in terms of valve positioning and retention, though it's crucial to note that the detented positions are not suitable for load holding but only for temporary shifting. The valve is capable of handling a maximum flow capacity of 12 gpm (45 L/min) and can withstand a maximum operating pressure of up to 5000 psi (350 bar). The manual operation is facilitated through a knob that should be operated directly by hand without any mechanical modifications or attachments. The design also includes Sun's floating style construction which helps prevent internal part binding due to excessive installation torque or variations in cavity/cartridge machining. Additionally, the product specifications detail an operating torque of 10 lbf.in (1.2 Nm), valve hex size of 7/8 in. (22.2 mm), and an installation torque requirement between 30 \u2013 35 lbf.ft (41 \u2013 47 Nm). The mechanical life expectancy of the manual control assembly is approximately 7,000 cycles, ensuring durability and reliability for its designated intermittent applications. This robust construction and thoughtful design make the DMDMLRN an efficient solution for manual hydraulic flow direction control in various configurations where temporary intervention is needed.
