The Sun Hydraulics DMDADRV814 (DMDADRV814) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve is engineered for robust functionality with a fatigue rating up to 5000 psi (350 bar), making it suitable for demanding applications. The valve features closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times particularly beneficial in pilot control applications where capacity is less critical. With a maximum flow capacity of 12 gpm (45 L/min) and a typical response time of 50 ms, the DMDADRV814 ensures efficient operation in hydraulic systems. Its wet armature design allows the working fluid to surround the armature, helping manage heat during prolonged coil energization but requires attention regarding fluid compatibility to prevent breakdown and varnish formation. It uses EPDM seals specifically for phosphate ester fluids, avoiding exposure to petroleum-based products which can degrade the seals. This model incorporates interchangeable coils from Sun's Series 1 solenoid products, offering flexibility in maintenance and replacement procedures. Additionally, it features Sun\u2019s floating style construction which minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. Key specifications include a maximum operating pressure of 5000 psi (350 bar), switching frequency up to 15000 cycles/hr, and very minimal valve leakage under high pressure conditions. The manual override mechanism requires minimal force, facilitating ease of temporary actuation while maintaining durability with an estimated mechanical life of approximately 7,000 cycles. This makes DMDADRV814 an ideal choice for advanced hydraulic systems requiring reliable directional control with high cycling frequency and precision response characteristics.
