The Sun Hydraulics DMDATNV914 (DMDATNV914) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve is engineered to operate efficiently with a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 12 gpm (45 L/min). The DMDATNV914 features a unique closed transition between spools B and R, enhancing performance by ensuring faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. This model is distinguished by its wet armature design, allowing the working fluid to surround the armature which helps in heat management but requires careful consideration of the fluid type to prevent breakdown and varnishing. It's compatible with EPDM seals specifically for use with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. Additionally, the DMDATNV914 incorporates Sun\u2019s floating style construction which minimizes internal parts binding due to excessive installation torque or cavity/cartridge machining variations. The manual override feature included in models with D or L control is designed for temporary actuation with a mechanical life expectancy of about 7,000 cycles. For ease of maintenance and compatibility across systems, this model\u2019s coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Key specifications include a typical response time of 50 ms, maximum valve leakage at 110 SUS (24 cSt) of 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar), and a switching frequency capable of up to 15,000 cycles per hour. This makes the DMDATNV914 an ideal choice for demanding applications requiring high reliability and precise control.
