The Sun Hydraulics DMDADRV514 (DMDADRV514) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust applications, featuring a fatigue rating of 5000 psi (350 bar) for the solenoid tube assembly. It is particularly suited for use as pilot controls due to its closed transition between spools B and R, which ensures faster and more consistent response times without the need for minimum hydraulic pressure. The DMDADRV514 model incorporates a wet armature design where the working fluid surrounds the armature, potentially affecting fluid integrity if exposed to prolonged heat. It's compatible with EPDM seals specifically for systems using phosphate ester fluids; however, these seals are susceptible to damage by petroleum-based substances. The manual override in models with D or L control is designed for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. Interchangeability of coils with other Sun Series 1 solenoid products adds versatility to this model. The floating style construction of the valve minimizes internal parts binding which might occur due to excessive installation torque or cavity/cartridge machining variations. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity of up to 12 gpm (45 L/min), and rapid response times typically around 50 ms. This valve is ideal for applications requiring precise control and reliability in hydraulic systems, ensuring efficient operation across various setups without compromising on performance.
