The Sun Hydraulics DMDALAN71299 (DMDALAN71299) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve is well-suited for applications requiring a robust response and tight control over fluid handling. It features a fatigue rating of 5000 psi (350 bar), making it ideal for high-pressure operations. The valve's spools, designated B and R, are closed during the transition between positions, enhancing performance by providing faster and more consistent response times at the cost of lower flow capacity. This characteristic is particularly beneficial in pilot control applications where flow capacity is less critical. The DMDALAN71299 operates without requiring a minimum hydraulic pressure, thereby facilitating its use in various hydraulic systems without additional pressure support. Equipped with EPDM seals, this model is specifically configured for use with phosphate ester fluids; however, it should not be exposed to petroleum-based fluids as they can damage the seals. The manual override feature included in models with D or L control uses a detent mechanism designed primarily for temporary actuation and has a mechanical life expectancy of about 7,000 cycles. This valve also incorporates Sun Hydraulics' floating style construction which minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. Additionally, it supports interchangeable coils from other Sun Series 1 solenoid products which can be mounted on the tube in either direction to accommodate different setup requirements. With specifications like a maximum operating pressure of 5000 psi (350 bar), capacity up to 12 gpm (45 L/min), and rapid response times typically around 50 ms, the DMDALAN71299 is engineered to meet demanding hydraulic control tasks efficiently and reliably.
