The Sun Hydraulics DMDALBN512 (DMDALBN512) is a high-performance solenoid-operated 3-way, 2-position cartridge. This direct-acting, balanced spool directional valve is specifically designed to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). The valve features a unique closed transition between Spools B and R, enhancing performance by providing faster and more consistent response times, particularly suitable for applications as pilot controls where capacity is less critical. Constructed with durability in mind, the DMDALBN512 incorporates Sun's floating style construction that prevents internal parts binding from excessive installation torque or variations in cavity/cartridge machining. It also utilizes a wet armature design where the working fluid surrounds the armature, helping manage heat but requiring consideration for fluid type due to potential breakdowns at high temperatures. The manual override feature in this model, equipped with D or L control options, supports temporary actuation with a mechanical life expectancy around 7,000 cycles. Additionally, this model's coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction for flexible installation options. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended. However, these seals must not be exposed to petroleum-based fluids as they can cause damage. The valve's robust design includes features such as minimal leakage at high pressures (5 in\u00b3/min at 3000 psi) and quick response times typically around 50 ms. Overall, the Sun Hydraulics DMDALBN512 valve is an efficient solution for various hydraulic applications requiring reliable directional control and rapid response under high pressure conditions.
