The Sun Hydraulics DMDAMPV914N (DMDAMPV914N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. Designed as a direct-acting, balanced spool directional valve, it is particularly suited for applications requiring robust control and reliability. The valve features a fatigue rating of 5000 psi (350 bar), making it ideal for high-pressure environments. It operates without the need for minimum hydraulic pressure, enhancing its versatility in various hydraulic systems. The DMDAMPV914N incorporates closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. The manual override feature included in models with D or L control is designed for temporary actuation, with a mechanical life expectancy of around 7,000 cycles. This model utilizes EPDM seals suitable for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they could degrade. Additionally, the valve employs a wet armature design where the working fluid surrounds the armature, potentially impacting fluid integrity under prolonged coil energization. Its interchangeable coils with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement. The valve\u2019s construction incorporates Sun\u2019s floating style to minimize internal part binding due to installation torque or cavity-cartridge machining variations. Key specifications include a flow capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum leakage at 3000 psi set at 5 in\u00b3/min. The DMDAMPV914N also supports a switching frequency up to 15000 cycles/hr and requires manual override force of approximately 5 lbs at 1000 psi per port. This model's compact and efficient design ensures reliable performance across various hydraulic applications.
