The Sun Hydraulics DMDAXRV211 (DMDAXRV211) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for versatile hydraulic applications. This direct-acting, balanced spool directional valve ensures reliable control in various systems, operating effectively with a maximum pressure of 5000 psi (350 bar) and a flow capacity of 12 gpm (45 L/min). The DMDAXRV211 features closed transitions between spool positions B and R, enhancing performance by providing faster and more consistent response times, especially suitable for pilot control applications where capacity is less critical. Notably, the valve operates without requiring a minimum hydraulic pressure, which allows for flexibility in low-pressure applications. It includes options for manual override controls (D, L, T) with a mechanical life expectancy of about 7,000 cycles. These manual overrides are intended primarily for temporary actuation. The valve's construction incorporates Sun Hydraulics' floating style design to reduce risks of internal parts binding due to installation torque or machining variations. The DMDAXRV211 uses EPDM seals configured specifically for systems using phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. Its solenoid tube assembly is fatigue rated and utilizes a wet armature design where the working fluid surrounds the armature. This design consideration is crucial as prolonged energization can lead to fluid breakdown at high temperatures. Additionally, the solenoid coils are interchangeable with other Series 1 products from Sun Hydraulics and can be mounted in either direction on the tube. This model's robust design also accommodates frequent switching operations up to 15,000 cycles per hour and has typical response times of around 50 ms. With its compact size and weight (.60 lb/0.30 kg), the DMDAXRV211 offers an efficient solution for dynamic hydraulic system needs while ensuring durability and reliability in demanding environments.
