The Sun Hydraulics DMDATRV814N (DMDATRV814N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust and efficient hydraulic system management. This direct-acting, balanced spool directional valve features a fatigue rating of 5000 psi (350 bar), making it suitable for high-pressure applications. The DMDATRV814N ensures closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. The valve operates without the need for minimum hydraulic pressure and includes manual override options with a mechanical life expectancy of about 7,000 cycles. Specifically configured cartridges with EPDM seals are used in systems containing phosphate ester fluids; however, these seals must avoid exposure to petroleum-based substances to prevent damage. Another notable feature is its wet armature design which exposes the working fluid to coil-generated heat, potentially affecting fluid integrity over prolonged periods. Interchangeability of coils with other Sun Series 1 solenoid products adds versatility to this model, allowing coils to be mounted in either direction on the tube. Additionally, the DMDATRV814N incorporates Sun's floating style construction which minimizes internal part binding due to installation torque or machining variations in cavity/cartridge setups. This model\u2019s specifications include a flow capacity of 12 gpm (45 L/min), rapid response times typically around 50 ms, and a maximum operating pressure of 5000 psi (350 bar). It also supports a high switching frequency up to 15,000 cycles/hr and requires minimal manual override force. The compact design weighs approximately 0.60 lb (0.30 kg) and adheres strictly to precise installation torque specifications ensuring reliability and ease of use in various hydraulic system configurations.
