The Sun Hydraulics DMDAXPN212 (DMDAXPN212) is a solenoid-operated 3-way, 2-position cartridge valve, characterized by its direct-acting, balanced spool directional control mechanism. Engineered for robust performance, this valve features a fatigue rating suitable for 5000 psi (350 bar) service. It is particularly noted for its closed transitions between Spools B and R which enhance performance by ensuring faster and more consistent response times during operation. This makes the valve ideal for applications as pilot controls where capacity is less critical. The DMDAXPN212 operates without requiring a minimum hydraulic pressure, facilitating its use in a variety of fluid power applications. The manual override options available with the D or L control are designed primarily for temporary actuation, supporting mechanical life expectancies of approximately 7,000 cycles. Additionally, this model employs EPDM seals which are compatible with phosphate ester fluids but must avoid contact with petroleum-based substances to prevent damage. Another significant feature of the DMDAXPN212 is its wet armature design; the working fluid surrounds the armature which can be an important consideration if the coil remains energized over extended periods. The potential heat exposure could degrade certain types of hydraulic fluids. For maintenance and customization ease, coils on this model are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction. This valve also incorporates Sun's floating style construction which minimizes risks associated with internal parts binding due to excessive installation torque or machining variations in cavity/cartridge setups. With operational capacities reaching up to 12 gpm (45 L/min) and maximum operating pressures sustained at 5000 psi (350 bar), the DMDAXPN212 offers reliable switching capabilities up to 15,000 cycles per hour while maintaining stringent leak control standards.
