The Sun Hydraulics DMDAMRN812N (DMDAMRN812N) is a solenoid-operated 3-way, 2-position cartridge valve that excels in applications requiring direct-acting, balanced spool directional control. This model is particularly suitable for use as pilot controls due to its closed transition between positions B and R, which ensures faster and more consistent response times without the need for minimum hydraulic pressure. The DMDAMRN812N features a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service, enhancing its durability and performance in demanding environments. This valve also incorporates a wet armature design, allowing it to operate efficiently by cooling the armature with the working fluid, although care must be taken with fluid selection as certain types can degrade under prolonged exposure to heat. The compatibility of coils across Sun Series 1 solenoid products offers flexibility in maintenance and replacement procedures. Furthermore, the construction utilizes Sun's floating style to minimize internal binding caused by excessive installation torque or variations in cavity/cartridge machining. The manual override feature of this model is designed for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. It supports a flow capacity of up to 12 gpm (45 L/min) and can handle maximum operating pressures up to 5000 psi (350 bar). With rapid response times typically around 50 ms and a switching frequency capable of reaching up to 15,000 cycles per hour, the DMDAMRN812N is an efficient solution for dynamic systems requiring precise control and reliability.
