The Sun Hydraulics DMDMTNN (DMDMTNN) is a manually operated, 2-position, 3-way directional cartridge valve designed for controlling the direction of flow in hydraulic circuits. It features a direct-acting, balanced spool mechanism which ensures reliable performance under various conditions. This model incorporates Sun's TwistLock manual override mechanism, intended for intermittent and infrequent use only, making it ideal as a manual override within hydraulic systems. The DMDMTNN offers multiple control options including momentary-twist (option T), detent-lock (option L), and dual-operation (option D). The momentary-twist control allows for temporary shifting of the valve by twisting the knob clockwise; upon release, the valve automatically returns to its original position. The detent-lock option enables the valve to stay in a mechanically detented position when twisted counterclockwise until manually reset. The dual-operation control combines both functionalities depending on the direction of the twist. It's important to note that these detented positions are not suitable for load holding but are meant for temporary shifts. Constructed with Sun\u2019s floating style design, this valve minimizes potential internal binding caused by excessive installation torque or variations in cavity/cartridge machining. It supports a maximum flow capacity of 12 gpm (45 L/min) and can handle pressures up to 5000 psi (350 bar). The operational characteristics include an operating torque of 10 lbf.in (1.2 Nm), and it requires an installation torque between 30 - 35 lbf.ft (41 - 47 Nm). The valve is designed with a hex size of 7/8 in. (22.2 mm) and uses Viton seals for enhanced durability under high-pressure conditions. This product is particularly suited for applications where manual control of hydraulic flow is necessary on an occasional basis, offering robust performance with reliable manual override options in critical situations.
