The Sun Hydraulics DMDATNV72499 (DMDATNV72499) is a solenoid-operated 3-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. This high-performance valve is specifically constructed for robust applications requiring precise control of hydraulic flow. With a maximum operating pressure of 5000 psi (350 bar) and a capacity to handle up to 12 gpm (45 L/min), it is ideal for various hydraulic systems. The DMDATNV72499 features closed transitions between positions B and R, enhancing performance by ensuring faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. This model incorporates a wet armature design, meaning the working fluid surrounds the armature which can be significant when considering fluid compatibility and coil heat exposure. It is important to note that cartridges configured with EPDM seals are specifically designed for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. The manual override feature in models with D or L control utilizes a detent mechanism designed for temporary actuation, with an expected mechanical life of around 7,000 cycles. Additionally, the interchangeable coils compatible with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement processes. Installation considerations include Sun\u2019s floating style construction which minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. This model also supports a switching frequency of up to 15,000 cycles/hr and features rapid response times typically around 50 ms. Overall, the DMDATNV72499 valve is engineered to provide reliable and efficient directional control in sophisticated hydraulic systems requiring high-pressure operation and precise fluid handling capabilities.
