The Sun Hydraulics DMDALAN211 (DMDALAN211) is a solenoid-operated 3-way, 2-position cartridge valve, designed for high-performance applications requiring precise control and reliability. This direct-acting, balanced spool directional valve is well-suited to functions where rapid and consistent response times are critical. Its design includes a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar), making it robust for demanding environments. The valve features closed transitions between positions B and R, optimizing performance by ensuring no drop in pressure during switching. This characteristic is especially beneficial in pilot control applications where capacity isn't a primary concern but speed and consistency of response are crucial. The manual override options available with the D or L control on this model are intended for temporary actuation, with a mechanical life expectancy of around 7,000 cycles. 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 will degrade. The wet armature design of the valve means that the working fluid surrounds the armature which can be an important consideration if the coil remains energized over extended periods due to potential breakdown of certain fluids like water-glycol mixtures at high temperatures. Interchangeability of coils with other Sun Series 1 solenoid products adds to the versatility of this model, alongside features like Sun's floating style construction which minimizes internal parts binding due to installation variances or machining differences. The DMDALAN211 supports up to 12 gpm (45 L/min) flow capacity and offers rapid response times typically around 50 ms. With its compact size and robust build quality, this valve ensures reliable operation in a variety of hydraulic systems needing precise directional control.
