The Sun Hydraulics DMDADRN524 (DMDADRN524) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust and efficient hydraulic control in various applications. This direct-acting, balanced spool directional valve is notable for its ability to operate without minimum hydraulic pressure, featuring a fatigue rating of 5000 psi (350 bar) for the solenoid tube assembly. The valve's design includes closed spools B and R during the transition between two positions, enhancing performance by providing faster and more consistent response times especially when used as pilot controls. Equipped with a wet armature design, the DMDADRN524 ensures that the working fluid surrounds the armature which helps in heat management but requires careful selection of fluids to prevent breakdowns that could lead to varnish formation affecting functionality. This model supports interchangeable coils with other Sun Series 1 solenoid products and can be mounted on the tube in either direction which increases flexibility in usage. The manual override feature included in models with D or L control is intended for temporary actuation with a mechanical life expectancy of about 7,000 cycles. For environments utilizing phosphate ester fluids, cartridges configured with EPDM seals are recommended; however, these seals must be protected from exposure to petroleum-based fluids which can cause damage. Additional key specifications include a maximum operating capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum valve leakage at 110 SUS (24 cSt) being significantly low at around 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). The valve also boasts a switching frequency of up to 15,000 cycles per hour. With its robust construction and precise engineering, the Sun Hydraulics DMDADRN524 offers reliable performance for specialized hydraulic applications requiring precise control and durability.
