The Sun Hydraulics DMDALAV948 (DMDALAV948) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic applications. This direct-acting, balanced spool directional valve ensures reliable control in various hydraulic systems. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min), it is well-suited for demanding environments. The valve features a quick response time of approximately 50 ms and supports up to 15,000 switching cycles per hour, making it ideal for high-frequency operations. The DMDALAV948 incorporates a wet armature design, where the working fluid surrounds the armature, aiding in heat dissipation during prolonged energization but requiring careful selection of fluids to avoid breakdown and varnish formation. It uses EPDM seals specifically for compatibility with phosphate ester fluids; however, these seals are vulnerable to damage from petroleum-based fluids. This model benefits from Sun Hydraulics' floating style construction which minimizes internal parts binding due to excessive installation torque or machining variations in the cavity/cartridge. It also features interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. For manual override operations, the valve includes a detent mechanism designed for temporary actuation with an expected mechanical life of about 7,000 cycles. The manual override requires minimal force (approximately 5 lbs at 1000 psi), enhancing ease of use under various pressure conditions. Overall, the Sun Hydraulics DMDALAV948 valve provides reliable performance with fast and consistent response times suitable for sophisticated hydraulic systems requiring precise control and durability.
