The Sun Hydraulics DMDAMPV71219 (DMDAMPV71219) is a solenoid-operated 3-way, 2-position cartridge valve that excels in direct-acting, balanced spool directional control. Designed for high-pressure applications, this valve is fatigue rated for up to 5000 psi (350 bar), making it suitable for rigorous hydraulic systems. The DMDAMPV71219 features closed transitions between spools B and R, enhancing performance by ensuring faster and more consistent response times particularly useful in pilot control applications where capacity is less critical. This model is equipped with a wet armature design; the working fluid surrounds the armature which helps in heat absorption from the coil but requires consideration of fluid type to avoid breakdown and varnish formation. It supports a maximum flow capacity of 12 gpm (45 L/min) and offers quick response times typically around 50 ms. The valve's manual override function, with a force requirement of about 5 lbs at 1000 psi for port 1, is designed primarily for temporary actuation with an expected mechanical life of around 7,000 cycles. With interchangeable coils compatible across Sun Series 1 solenoid products and a floating style construction to minimize internal binding risks, the DMDAMPV71219 provides flexibility and reliability in installation and operation. The cartridges configured with EPDM seals are specifically intended for systems using phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. This model also includes features like a maximum operating pressure of up to 5000 psi (350 bar), typical switching frequency of about 15000 cycles per hour, and minimal valve leakage at high pressures ensuring efficient performance across various operational conditions.
