The Sun Hydraulics DMDAMRV814 (DMDAMRV814) is a solenoid-operated 3-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. It is engineered to provide high-performance functionality with a fatigue rating for 5000 psi (350 bar) service. The valve's closed spool transition between positions B and R enhances performance by offering faster and more consistent response times, particularly beneficial in pilot control applications where capacity is less critical. This model operates without requiring a minimum hydraulic pressure, thus facilitating direct actuation. The manual override, available in models with D or L control, features a detent mechanism designed for temporary actuation and can endure approximately 7,000 cycles. The valve incorporates EPDM seals suitable for use with phosphate ester fluids; however, these seals are susceptible to damage from exposure to petroleum-based substances. A notable feature of the DMDAMRV814 is its wet armature design, where the working fluid envelopes the armature which may affect performance if the coil remains energized over extended periods\u2014particularly relevant when using water-glycol mixtures that could degrade under heat. The interchangeable coils compatible with other Sun Series 1 solenoid products offer flexible installation options. Additionally, this valve employs Sun's floating style construction to reduce risks of internal binding caused by excessive installation torque or cavity/cartridge machining discrepancies. Key specifications include a flow capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum switching frequency of 15,000 cycles per hour. The valve also supports manual override with specific force and stroke requirements and maintains minimal leakage at high pressures.
