The Sun Hydraulics DMDATBV612 (DMDATBV612) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust and precise control in hydraulic systems. It features a fatigue-rated solenoid tube assembly suitable for services up to 5000 psi (350 bar), ensuring reliability under high-pressure conditions. The valve's spools, B and R, are closed during the transition between two positions which enhances performance by providing faster and more consistent response times especially in pilot control applications where capacity is less critical. The DMDATBV612 operates without requiring a minimum hydraulic pressure, adding to its versatility across various applications. It incorporates manual override options with detent mechanisms designed for temporary actuation, with a mechanical life expectancy of around 7,000 cycles. The wet armature design of the valve means that the working fluid surrounds the armature; this is an important consideration as prolonged energization can lead to fluid degradation in certain cases. This model uses EPDM seals specifically suited for phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage these seals. The valve offers interchangeability of coils with other Sun Series 1 solenoid products and supports installation flexibility due to its floating style construction which minimizes internal parts binding from excessive installation torque or cavity/cartridge machining variations. Key specifications include a flow capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum leakage at 3000 psi set at 5 in\u00b3/min (80 cc/min). This model also features a manual override force requirement of approximately 5 lbs at 1000 psi for Port 1 and has a switching frequency capability up to 15000 cycles/hr.
