The Sun Hydraulics DMDADPN836 (DMDADPN836) is a solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool directional design. Engineered to function without minimum hydraulic pressure, this valve offers robust performance with its fatigue rating for 5000 psi (350 bar) service. It is specifically designed with closed transitions between Spools B and R, enhancing performance while sacrificing capacity which is not critical in pilot control applications where faster and more consistent response times are prioritized. This model incorporates a wet armature design allowing the working fluid to surround the armature, which could be significant when the coil is energized for extended periods as some fluids may degrade under prolonged exposure to heat. The valve's manual override mechanism, equipped on models with D or L control, has a mechanical life expectancy of about 7,000 cycles and is intended for temporary actuation only. For compatibility with different system fluids, cartridges configured with EPDM seals are suitable for use with phosphate ester fluids but should avoid exposure to petroleum-based substances that could damage the seals. Additionally, this model supports interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and rapid response times typically around 50 ms. The Sun floating style construction minimizes internal part binding due to installation torque or machining variations in cavity/cartridge setups. This model's practical applications benefit from its high switching frequency capability of up to 15,000 cycles per hour and its compact design ensures easy integration into various hydraulic systems.
