The Sun Hydraulics DMDALPV211 (DMDALPV211) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust and efficient hydraulic control. With a direct-acting, balanced spool configuration, this valve ensures reliable operation without the need for minimum hydraulic pressure. The solenoid tube assembly of the DMDALPV211 is fatigue rated for up to 5000 psi (350 bar), making it suitable for high-pressure applications. This model features closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, particularly useful in pilot control applications where capacity is less critical. The valve incorporates a wet armature design where the working fluid surrounds the armature, which can be crucial when considering fluid compatibility and coil temperature management during extended periods of energization. For manual override operations, the DMDALPV211 includes a detent mechanism designed for temporary actuation with a mechanical life expectancy of about 7,000 cycles. It also supports various manual control assemblies identified as D, L, and T options. The valve is compatible with EPDM seals for systems using phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided to prevent seal damage. Interchangeability of coils with other Sun Series 1 solenoid products offers flexibility in maintenance and replacement procedures. Additionally, its design includes Sun\u2019s floating style construction which minimizes internal parts binding due to installation torque or machining variations in cavity/cartridge setups. Key specifications include a flow capacity of 12 gpm (45 L/min), a typical response time of 50 ms, maximum operating pressure of 5000 psi (350 bar), and switching frequency up to 15,000 cycles per hour. This model also features manual override capabilities requiring minimal force and stroke adjustments for operational control.
