The Sun Hydraulics DMDALNN936 (DMDALNN936) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve is engineered with a fatigue rating suitable for services up to 5000 psi (350 bar), making it ideal for high-pressure environments. The DMDALNN936 features closed transitions between its two positions (Spools B and R), which enhances performance limits while reducing capacity\u2014suitable particularly when used as pilot controls where capacity is less critical. This valve operates without the need for a minimum hydraulic pressure, thus facilitating consistent and reliable performance across a range of conditions. It includes manual override options with detent mechanisms designed for temporary actuation; these are available in models equipped with D or L control. The mechanical life expectancy of these manual control assemblies is estimated at around 7,000 cycles. Designed with EPDM seals, the DMDALNN936 is optimized for use with phosphate ester fluids, although it should not be exposed to petroleum-based fluids which can damage the seals. Its wet armature design allows the working fluid to surround the armature, potentially affecting fluid properties if exposed to prolonged heat from an energized coil. Key specifications include a flow capacity of 12 gpm (45 L/min), typical response times of 50 ms, and maximum operating pressures of 5000 psi (350 bar). It also features interchangeable coils compatible with other Sun Series 1 solenoid products and incorporates Sun\u2019s floating style construction to minimize internal binding risks due to installation stresses or machining variations. This model's compact form factor and robust design make it an essential component in advanced hydraulic systems requiring precise control and durability.
