The Sun Hydraulics DMDAXPV (DMDAXPV) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. It features a direct-acting, balanced spool directional design that provides reliable operation without requiring a minimum hydraulic pressure. This valve is particularly suited for applications where rapid and consistent response times are critical, making it ideal for use as pilot controls. The DMDAXPV operates with a maximum capacity of 12 gpm (45 L/min) and can handle pressures up to 5000 psi (350 bar). Its robust construction includes a fatigue-rated solenoid tube assembly designed for demanding 5000 psi service environments. The valve's spools (B and R) are closed in transition between positions to enhance performance limits at the cost of lower capacity, which is typically not an issue in pilot control applications. This model incorporates Sun's floating style construction, minimizing internal part binding due to installation torque or machining variations. It also features interchangeable coils with other Sun Series 1 solenoid products, facilitating versatile use and maintenance. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended; however, these should not be exposed to petroleum-based fluids as they can damage the seals. Additional features include a manual override with a detent mechanism designed for temporary actuation and a mechanical life expectancy of approximately 7,000 cycles for models equipped with D, L, or T manual control assemblies. The wet armature design where the working fluid surrounds the armature can affect fluid properties if the coil remains energized for extended periods. This valve also boasts quick response times typically around 50 ms and has a maximum switching frequency of about 15,000 cycles per hour.
