The Sun Hydraulics DMDATPV712 (DMDATPV712) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for direct-acting operation with a balanced spool directional control mechanism. This valve is engineered to handle a maximum operating pressure of 5000 psi (350 bar) and is fatigue rated for demanding applications, ensuring robust performance in varied hydraulic systems. The DMDATPV712 features closed transitions between spool positions B and R, optimizing performance by providing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. This model's manual override options include detent mechanisms designed for temporary actuation, with a mechanical life expectancy of around 7,000 cycles. It incorporates EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. The design includes a wet armature setup where the working fluid surrounds the armature\u2014important to consider as prolonged energization can lead to heat buildup affecting fluid integrity. Interchangeability of coils with other Sun Series 1 solenoid products adds versatility in maintenance and replacement processes. Additionally, the valve's construction utilizes Sun's floating style design which minimizes internal parts binding that could result from excessive installation torque or cavity/cartridge machining variations. Key specifications include a flow capacity of 12 gpm (45 L/min), typical response times of 50 ms, and maximum leakage at 3000 psi rated at 5 in\u00b3/min (80 cc/min). The switching frequency can reach up to 15,000 cycles per hour. Installation requires specific torque settings between 30-35 lbf-ft (41-47 Nm), ensuring secure and reliable assembly in system configurations.
