The Sun Hydraulics DMDALNN236 (DMDALNN236) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve that excels in demanding hydraulic applications. This direct-acting, balanced spool directional valve is designed for fatigue-rated service at pressures up to 5000 psi (350 bar), ensuring reliable operation under high-pressure conditions. The valve features closed transitions between positions B and R, enhancing performance by providing faster and more consistent response times, especially suitable for pilot control applications where capacity is less critical. The DMDALNN236 operates without requiring a minimum hydraulic pressure, facilitating its use in a variety of systems with varying pressure conditions. It includes manual override options with detent mechanisms designed for temporary actuation; these are particularly useful during maintenance or emergency interventions. The mechanical life expectancy of the manual control assembly is around 7,000 cycles, indicating robust durability for repeated use. This model uses EPDM seals compatible with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they could degrade. The valve's wet armature design allows the working fluid to surround the armature which helps manage the heat generated by the coil but could lead to breakdowns in certain fluid types over extended periods of energization. Additional features include interchangeable coils with other Sun Series 1 solenoid products and a floating style construction that minimizes internal binding caused by installation stresses or machining variations. With a maximum flow capacity of 12 gpm (45 L/min) and rapid response times typical at 50 ms, the DMDALNN236 is well-suited for high-frequency switching applications up to 15,000 cycles per hour. This model not only promises efficiency and reliability but also versatility across various hydraulic setups.
