The Sun Hydraulics DMDADPN71219 (DMDADPN71219) is a high-performance solenoid-operated 3-way, 2-position cartridge valve, specifically designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve ensures reliable control of hydraulic flow with its closed spool transitions between two positions, enhancing performance by providing faster and more consistent response times. Ideal for pilot controls where capacity is less critical, this feature of the valve aids in achieving precise operation in various hydraulic setups. The DMDADPN71219 operates without requiring a minimum hydraulic pressure, making it highly versatile for different hydraulic conditions. It features a wet armature design; the working fluid surrounds the armature which can be susceptible to heat during prolonged energization, potentially affecting fluid properties over time. Users should consider fluid compatibility, especially with water-glycol mixtures which may degrade under heat. This model is compatible with EPDM seals suited for phosphate ester fluids but should avoid contact with petroleum-based fluids to prevent seal damage. The manual override mechanism incorporated within this valve is intended for temporary actuation and has a mechanical life expectancy of around 7,000 cycles. Furthermore, the interchangeability of coils with other Sun Series 1 solenoid products adds to its flexibility in system design and maintenance. The floating style construction of the valve minimizes internal part binding due to installation torque or machining variations in cavity/cartridge interfaces. With a maximum operating pressure capacity of 5000 psi (350 bar) and flow capacity up to 12 gpm (45 L/min), combined with swift response times typically around 50 ms and minimal leakage at high pressures, the Sun Hydraulics DMDADPN71219 offers a reliable solution for demanding hydraulic control applications.
