The Sun Hydraulics DMDADPV297 (DMDADPV297) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for use in hydraulic systems requiring precise control and robust operation. It features a fatigue rating of 5000 psi (350 bar), making it suitable for high-pressure applications. The valve operates with no minimum hydraulic pressure required, enhancing its versatility across various hydraulic systems. The DMDADPV297 boasts a rapid and consistent response time due to its closed transition between spool positions B and R, which also increases performance limits at the cost of lower capacity. This makes it ideal as pilot controls where capacity is less critical. The valve's manual override options include detent mechanisms (models with D or L control) designed for temporary actuation, with a mechanical life expectancy of approximately 7,000 cycles. For environments using phosphate ester fluids, cartridges equipped with EPDM seals are recommended to avoid damage from petroleum-based fluids. Additionally, the wet armature design of the valve ensures that the working fluid surrounds the armature, which is crucial in managing heat during prolonged coil energization. However, this can affect fluid integrity over time if not properly managed. Interchangeability of coils with other Sun Series 1 solenoid products offers flexibility in maintenance and upgrades, allowing coils to be mounted in either direction on the tube. The construction incorporates Sun's floating style to minimize internal parts binding due to installation torque or machining variations of cavity/cartridge. Key specifications include a flow capacity of 12 gpm (45 L/min), 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 adheres to cavity T11A and Series 1 standards by Sun Hydraulics.
