The Sun Hydraulics DMDALRV224 (DMDALRV224) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve operates without the need for minimum hydraulic pressure, ensuring reliable function under a variety of conditions. The valve features a unique closed transition between Spools B and R, enhancing performance by providing faster and more consistent response times, particularly beneficial when used as pilot controls. With a fatigue rating for 5000 psi (350 bar) service, the solenoid tube assembly of this model is built to withstand demanding operational requirements. The DMDALRV224 incorporates interchangeable coils from the Sun Series 1 solenoid products, which can be mounted in either direction to accommodate different installation needs. Additionally, this model utilizes a wet armature design where the working fluid surrounds the armature; this is crucial for understanding thermal effects during prolonged energization. The valve is equipped with EPDM seals suitable for systems using phosphate ester fluids; however, these seals must avoid exposure to petroleum-based fluids which could cause damage. The manual override feature present in models with D or L control is specifically designed for temporary actuation, supporting mechanical life expectancy around 7,000 cycles. For installation and maintenance ease, the DMDALRV224 uses Sun\u2019s floating style construction to minimize internal parts binding due to excessive installation torque or cavity/cartridge machining variations. This model also supports a maximum flow capacity of 12 gpm (45 L/min) and features rapid response times typically around 50 ms. It's designed to handle switching frequencies up to 15,000 cycles per hour and offers minimal leakage at high pressures making it an efficient choice for sophisticated hydraulic circuits requiring precise control and durability.
