The Sun Hydraulics DMDALRN214 (DMDALRN214) is a solenoid-operated 3-way, 2-position cartridge valve designed for efficient control in hydraulic systems. This direct-acting, balanced spool directional valve operates without the need for minimum hydraulic pressure, enhancing its reliability across various applications. It features a robust solenoid tube assembly that is fatigue rated for 5000 psi (350 bar), ensuring durability under high-pressure conditions. The valve's design includes closed transitions between Spools B and R, which enhances performance by providing faster and more consistent response times during operation. This characteristic makes the DMDALRN214 particularly suitable for use as pilot controls where capacity is less critical but speed and accuracy of response are paramount. Additionally, the valve incorporates a wet armature design; the working fluid surrounds the armature which can affect fluid integrity under prolonged energization. For maintenance or manual operation, it includes a detent mechanism in the manual override which is intended for temporary actuation with an expected mechanical life of approximately 7,000 cycles. The DMDALRN214 also supports interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. This model uses EPDM seals recommended for systems using phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it could damage the seals. The cartridge employs Sun's floating style construction to minimize internal parts binding caused by excessive installation torque or machining variations of cavity/cartridge. With a maximum operating pressure of 5000 psi and a flow capacity of 12 gpm (45 L/min), along with a rapid typical response time of 50 ms, this valve is optimized for high-performance applications requiring precise fluid control.
