The Sun Hydraulics DMDAMNN214 (DMDAMNN214) is a solenoid-operated 3-way, 2-position cartridge valve designed to be direct-acting with a balanced spool for directional control. It features a fatigue-rated solenoid tube assembly that can handle up to 5000 psi (350 bar), making it robust for high-pressure applications. The valve has specific configurations such as the B and R spools which are closed during the transition between their two positions, enhancing performance limits by providing faster and more consistent response times especially in pilot control applications where capacity is less critical. This model is unique in its operation as it does not require minimum hydraulic pressure to function effectively. It includes manual override options with D, L, or T control types, where the detent mechanism is designed for temporary actuation with a mechanical life expectancy of about 7,000 cycles. The valve is equipped with EPDM seals suitable for phosphate ester fluids; however, these seals must avoid exposure to petroleum-based fluids which can cause damage. The DMDAMNN214 utilizes a wet armature design allowing the working fluid to surround the armature which may affect fluid integrity if exposed to prolonged heat from coil energization. This model's coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Moreover, it incorporates Sun's floating style construction minimizing internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. Key specifications include a flow capacity of up to 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), and typical response time of approximately 50 ms. The valve also supports a switching frequency of up to 15000 cycles per hour and has manual override features requiring minimal force. This compact yet powerful component weighs just about 0.60 lb (0.30 kg), fitting well into various hydraulic systems without adding significant weight or bulk.
