The Sun Hydraulics DNCAMAN72419 (DNCAMAN72419) is a solenoid-operated, 4-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This valve is engineered with a closed transition between positions to significantly reduce oil loss during shifting, making it particularly beneficial in pilot control circuits. It is optimized for use with port 3 as the inlet and port 1 as the tank, although reverse flow is possible but not recommended due to potential performance degradation. The solenoid tube assembly of this valve is fatigue-rated for service pressures up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. This model does not require a minimum hydraulic pressure for operation due to its direct actuation mechanism. It incorporates EPDM seals suitable for systems using phosphate ester fluids; however, these seals are incompatible with petroleum-based fluids. The wet armature design allows the working fluid to absorb heat generated by the coil, which could impact performance if energized for extended periods\u2014particularly in water-glycol mixtures that may degrade over time. The solenoid's magnetic design offers high efficiency and reliable valve shifting by providing substantial spool actuating force per watt expended. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted bidirectionally on the tube. Various coil termination and voltage options are available, including those with surge protection and weatherized variants offering IP69K ratings for enhanced environmental protection. The DNCAMAN72419 model features a floating style construction to minimize internal binding from installation torque or machining variations. It supports a maximum flow capacity of 8 gpm (30 L/min) and operates efficiently with minimal leakage at specified conditions. The valve's robust construction allows it to handle up to 15,000 switching cycles per hour, making it suitable for demanding applications requiring frequent actuation.
