The Sun Hydraulics DMDALAV814N (DMDALAV814N) is a solenoid-operated 3-way, 2-position cartridge valve that offers robust performance for hydraulic systems. This direct-acting, balanced spool directional valve is designed to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of 12 gpm (45 L/min). It features a fatigue-rated solenoid tube assembly suitable for high-pressure service environments. The valve's construction includes spools B and R, which are closed during the transition between positions, enhancing performance by ensuring faster and more consistent response times especially when used as pilot controls. The incorporation of EPDM seals makes this model suitable for systems using phosphate ester fluids, although it should not be exposed to petroleum-based fluids as they can damage the seals. Additionally, the DMDALAV814N benefits from Sun Hydraulics' floating style construction which minimizes internal part binding caused by excessive installation torque or cavity/cartridge machining variations. The manual override mechanism in models with D or L control is designed for temporary actuation with a mechanical life expectancy of about 7,000 cycles. This valve also features interchangeable coils with other Sun Series 1 solenoid products and supports a switching frequency of up to 15,000 cycles per hour. The manual override requires an actuation force of approximately 5 lbs at 1000 psi at Port 1. With its quick response time typically around 50 ms and minimal maximum valve leakage at high pressures, the DMDALAV814N is engineered for efficient and reliable operation in various hydraulic applications.
