The Sun Hydraulics DMDAMBN828 (DMDAMBN828) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve that excels in applications requiring precise control and reliability. This direct-acting, balanced spool directional valve is designed to operate seamlessly without the need for a minimum hydraulic pressure, enhancing its versatility across various hydraulic systems. With a robust fatigue rating of 5000 psi (350 bar), the valve ensures durability and consistent performance under demanding conditions. The DMDAMBN828 features closed transitions between its two positions (Spools B and R), which minimizes leakage and improves response times\u2014ideal for pilot controls where capacity is less critical but speed and consistency are paramount. The manual override options available with this model include detent mechanisms designed for temporary actuation, supporting a mechanical life expectancy of about 7,000 cycles. Specifically engineered for systems using phosphate ester fluids, this valve incorporates EPDM seals to prevent damage from petroleum-based substances. Its wet armature design allows the working fluid to surround the armature, which could be crucial when considering the thermal effects during prolonged energization of the coil. The valve's construction also features Sun's floating style design to reduce risks associated with internal part binding due to installation variances or machining errors. This model boasts a maximum operating pressure of 5000 psi and a flow capacity of up to 12 gpm (45 L/min). It offers rapid response times typically around 50 ms and maintains low leakage rates even at high pressures. Additionally, it supports interchangeable coils with other Sun Series 1 solenoid products and can handle switching frequencies up to 15,000 cycles per hour. Installation specifications include a hex size of 7/8 in (22.2 mm) and an installation torque range of 30-35 lbf ft (41-47 Nm), ensuring easy integration into various setups without specialized adjustments.
