The Sun Hydraulics DMDALRN736 (DMDALRN736) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve is engineered to operate seamlessly without minimum hydraulic pressure, enhancing its utility in a variety of applications. The valve features spools B and R which remain closed during the transition between positions, optimizing performance by providing faster and more consistent response times, particularly suitable for pilot controls where capacity is less critical. The construction of the DMDALRN736 incorporates a wet armature design, meaning the working fluid surrounds the armature which can be significant when exposed to heat from prolonged coil energization. This design consideration is crucial when using fluids like water-glycol mixtures that may degrade under high temperatures. Additionally, this model uses EPDM seals specifically for systems with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. With a robust manual override feature equipped on models with D or L control, the valve provides temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. It supports a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min). The response time is typically swift at around 50 ms. This cartridge also benefits from Sun\u2019s floating style construction which minimizes internal parts binding due to installation torque or machining variations in the cavity/cartridge setup. Coils used in this model are interchangeable with other Sun Series 1 solenoid products and can be mounted in either orientation on the tube. This flexibility along with its technical specifications makes the DMDALRN736 an efficient choice for demanding hydraulic applications requiring reliable directional control and rapid switching capabilities.
