The Sun Hydraulics DMDADRV936 (DMDADRV936) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust and efficient hydraulic control. This direct-acting, balanced spool directional valve is characterized by its ability to operate without minimum hydraulic pressure and features a fatigue rating for up to 5000 psi (350 bar) service. The valve's construction includes spools B and R which are closed during the transition between positions, enhancing performance at the cost of capacity\u2014a trade-off that benefits applications requiring fast and consistent response times rather than high flow capacity. The DMDADRV936 incorporates a wet armature design where the working fluid surrounds the armature. This setup facilitates heat management when the coil is energized for extended periods but requires careful selection of fluids to prevent breakdown and varnish formation that could impair valve function. The valve is compatible with EPDM seals suitable for phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage these seals. Featuring interchangeable coils with other Sun Series 1 solenoid products, this model offers flexibility in maintenance and replacement processes. It also employs Sun's floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 12 gpm (45 L/min), the DMDADRV936 provides reliable performance in various hydraulic systems. It also has a rapid response time of approximately 50 ms and allows manual override with minimal force requirement. The manual override mechanism, particularly useful in temporary actuation scenarios, has a mechanical life expectancy of about 7,000 cycles, ensuring durability and long-term reliability in demanding operational conditions.
