The Sun Hydraulics DMDATNV924N (DMDATNV924N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed to operate optimally under a maximum pressure of 5000 psi (350 bar) and offers a flow capacity of up to 12 gpm (45 L/min). The valve features a fast response time of approximately 50 ms and is built to handle switching frequencies up to 15,000 cycles per hour. Engineered for robustness and reliability, the DMDATNV924N incorporates a wet armature design where the working fluid surrounds the armature. This characteristic is crucial for applications where the valve might be continuously energized, as it aids in managing the heat generated by the coil. However, users should note that certain fluids like water-glycol mixtures may degrade at higher temperatures, potentially affecting performance over time. The valve's manual override option includes a detent mechanism designed for temporary actuation with an expected mechanical life of about 7,000 cycles. Additionally, it supports manual override forces requiring approximately 5 lbs at 1000 psi for Port 1. The DMDATNV924N also benefits from Sun Hydraulics' floating style construction which minimizes internal parts binding\u2014a common issue in valves due to excessive installation torque or cavity-cartridge machining variations. This model uses EPDM seals suitable for systems containing phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. For maintenance or replacements, specific seal kits like Viton: 990411006 for cartridges and Viton: 990770006 for coils are available. Overall, the Sun Hydraulics DMDATNV924N offers precise control and durability for demanding hydraulic applications where high pressure and consistent performance are critical. It is an excellent choice for systems requiring reliable directional control with minimal transition leakage and optimal thermal management.
