The Sun Hydraulics DMDALRV212 (DMDALRV212) is a solenoid-operated 3-way, 2-position cartridge valve, characterized by its direct-acting, balanced spool design. This valve operates with no minimum hydraulic pressure required, making it highly effective for various applications. The DMDALRV212 features a fatigue rating for service up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. Its closed transition between Spools B and R during operation enhances performance by providing faster and more consistent response times, especially useful in pilot control setups where capacity is less critical. The valve's manual override mechanism is equipped with a detent designed for temporary actuation, supporting manual operations when necessary. With an expected mechanical life of approximately 7,000 cycles for the D, L, and T manual control assembly options, this model promises reliability over a considerable duration. The wet armature design utilized in this model means that the working fluid surrounds the armature; however, care must be taken as prolonged energization can lead to fluid degradation at elevated temperatures. Configured cartridges with EPDM seals are specifically intended for systems using phosphate ester fluids; these seals must avoid exposure to petroleum-based substances to prevent damage. Additionally, the valve supports interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The floating style construction incorporated into the design minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This model has a flow capacity of up to 12 gpm (45 L/min) and features rapid typical response times of about 50 ms. It also maintains low leakage rates even under high pressures and offers a switching frequency capable of handling up to 15,000 cycles per hour. Installation specifications include a solenoid tube diameter of .75 inches (19 mm) and an installation torque between 30 - 35 lbf ft (41 - 47 Nm), making it adaptable to various setups without requiring extensive modifications.
