The Sun Hydraulics DMDALNV614 (DMDALNV614) is a high-performance solenoid-operated 3-way, 2-position cartridge valve, designed for direct-acting and balanced spool directional control. With a robust construction that includes a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service, this valve is engineered to deliver precise control and reliability in hydraulic systems. The DMDALNV614 features closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. This model does not require a minimum hydraulic pressure to operate, making it versatile for various applications. It incorporates manual override options with a detent mechanism designed for temporary actuation, supporting up to approximately 7,000 cycles. Special attention is given to the compatibility of system fluids; cartridges with EPDM seals are specifically intended for use with phosphate ester fluids and should avoid exposure to petroleum-based products which could degrade the seals. The DMDALNV614 also utilizes a wet armature design allowing the working fluid to cool the armature, although prolonged energization should be monitored as it may affect fluid integrity. Interchangeability of coils with other Sun Series 1 solenoid products adds flexibility in maintenance and system design. Additionally, the valve features Sun\u2019s floating style construction which minimizes internal part binding due to installation variances or machining discrepancies. Technical specifications include a flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum operating pressure of 5000 psi (350 bar). The valve\u2019s design ensures minimal leakage at high pressures and can handle up to 15,000 switching cycles per hour. Installation requires specific torque settings and manual override involves minimal force, facilitating ease of use in field operations.
