The Sun Hydraulics DMDAMPN836 (DMDAMPN836) is a high-performance solenoid-operated 3-way, 2-position cartridge valve, specifically designed for robust hydraulic applications. This direct-acting, balanced spool directional valve operates without the need for minimum hydraulic pressure, enhancing its versatility across various systems. The model features a fatigue-rated solenoid tube assembly capable of handling services up to 5000 psi (350 bar), making it suitable for demanding environments. The DMDAMPN836 incorporates closed transitions between Spools B and R, optimizing performance by ensuring faster and more consistent response times, particularly beneficial in pilot control applications where capacity is less critical. The wet armature design of the valve allows the working fluid to surround the armature, which is crucial for heat management but requires consideration of fluid characteristics to prevent breakdown and varnish formation. This model is compatible with EPDM seals intended for use with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage these seals. Additionally, the DMDAMPN836 offers interchangeable coils with other Sun Series 1 solenoid products and features a floating style construction that minimizes internal part binding due to installation torque or cavity/cartridge machining variations. Key specifications include a maximum flow capacity of 12 gpm (45 L/min), a typical response time of 50 ms, and manual override options that are designed for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. The compact design weighs just 0.60 lb (0.30 kg) and can handle switching frequencies up to 15000 cycles/hr. This model's adaptability and durability make it an excellent choice for sophisticated hydraulic systems requiring reliable directional control and rapid response capabilities.
