The Sun Hydraulics DMDADPV514 (DMDADPV514) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve ensures reliable operation with its fatigue-rated solenoid tube assembly for services up to 5000 psi (350 bar). The valve features closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times, especially suitable for pilot controls where capacity is less critical. The DMDADPV514 operates without requiring a minimum hydraulic pressure, which enhances its versatility in various system configurations. Models equipped with the D or L control include a detent mechanism in the manual override intended for temporary actuation, supporting a mechanical life expectancy of approximately 7,000 cycles. It is important to note that cartridges configured with EPDM seals should be used exclusively with phosphate ester fluids as exposure to petroleum-based fluids can damage these seals. This valve incorporates a wet armature design where the working fluid surrounds the armature; this aspect needs consideration as prolonged coil energization can lead to fluid degradation at high temperatures. The design also features interchangeable coils compatible with other Sun Series 1 solenoid products and includes Sun's floating style construction which minimizes internal parts binding due to installation torque or machining variations. With a maximum operating pressure of 5000 psi and a capacity of 12 gpm (45 L/min), the DMDADPV514 is suitable for demanding applications requiring precise control and reliability. Additional specifications include a typical response time of 50 ms, maximum valve leakage at 3000 psi rated at 5 in\u00b3/min., and a manual override force requirement of 5 lbs at 1000 psi. This model\u2019s robust construction and operational flexibility make it an excellent choice for specialized hydraulic system applications where high performance and durability are essential.
