The Sun Hydraulics DMDADPV214N (DMDADPV214N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve ensures reliable operation without requiring a minimum hydraulic pressure. It features a robust design with a fatigue rating of 5000 psi (350 bar), making it suitable for demanding applications. The valve's solenoid tube assembly is specifically engineered to handle high pressures, and the spools B and R maintain closure during transitions between positions to enhance performance limits at the cost of lower capacity. This characteristic is particularly beneficial in pilot control applications where rapid and consistent response times are critical. The manual override included in models with D or L control is intended for temporary actuation, with a mechanical lifespan of approximately 7,000 cycles. Configurations with EPDM seals are optimized for use with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. The wet armature design of the valve helps manage the heat generated by the coil but requires consideration regarding fluid selection as some may degrade under prolonged exposure to heat. This valve model also benefits from interchangeable coils within Sun\u2019s Series 1 solenoid products and can be mounted in either direction on the tube. It incorporates Sun\u2019s floating style construction which minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With a flow capacity of 12 gpm (45 L/min) and quick response time typically around 50 ms, it is an efficient choice for various hydraulic applications needing precise flow management and directional control.
