The Sun Hydraulics DMDATRN548 (DMDATRN548) is a solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This valve is specifically engineered to be fatigue rated for up to 5000 psi (350 bar), making it suitable for high-pressure applications. The spools B and R are closed in the transition between their two positions, which enhances performance limits at the cost of lower capacity. However, this characteristic is advantageous in pilot control applications where capacity is less critical, allowing for faster and more consistent response times. The DMDATRN548 operates without requiring a minimum hydraulic pressure, facilitating its use in a variety of fluid power systems. It includes options for manual override controls designated as D, L, and T types; these controls are intended for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. The valve's design incorporates EPDM seals configured specifically for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. A notable feature of this model is its wet armature design where the working fluid surrounds the armature. This setup needs consideration if the coil remains energized over long periods due to potential breakdowns in certain types of hydraulic fluids at elevated temperatures. The valve supports interchangeable coils from other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, the DMDATRN548 utilizes Sun\u2019s floating style construction which minimizes internal parts binding that could result from excessive installation torque or variations in cavity/cartridge machining. This model also offers robust switching capabilities up to 15,000 cycles per hour and has a typical response time of 50 ms. With its compact size and lightweight design (.60 lb or 0.30 kg), this valve provides an efficient solution for directional control in hydraulic systems while maintaining reliability and performance.
