The Sun Hydraulics DMDAMPN512 (DMDAMPN512) is a solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool directional control mechanism. This valve is specifically engineered for high-performance applications with its fatigue rating suitable for 5000 psi (350 bar) service. The unique design includes closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times especially when used as pilot controls. It operates without requiring a minimum hydraulic pressure, allowing for versatile use in various hydraulic systems. The DMDAMPN512 is equipped with manual override options including D, L, and T control types, each designed for temporary actuation with a mechanical life expectancy of about 7,000 cycles. It also incorporates EPDM seals suitable for phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. Another notable feature is its wet armature design where the working fluid surrounds the armature, necessitating consideration of fluid type due to potential heat exposure from prolonged coil energization. Interchangeability of coils with other Sun Series 1 solenoid products adds to the flexibility of this model, supporting various assembly configurations and orientations. The construction employs Sun\u2019s floating style to minimize internal binding risks caused by excessive installation torque or variations in cavity/cartridge machining. Key specifications include a flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum operating pressure of 5000 psi (350 bar). This model also supports a high switching frequency up to 15,000 cycles per hour and requires manual override force of approximately 5 lbs at 1000 psi for port activation.
