The Sun Hydraulics DMDAMBV636 (DMDAMBV636) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for direct-acting operation with a balanced spool directional control. This valve features a robust design with a fatigue rating for 5000 psi (350 bar) service, making it suitable for demanding hydraulic applications. It incorporates closed transitions between spool positions B and R, enhancing performance by ensuring faster and more consistent response times, particularly useful in pilot control applications where capacity is less critical. The DMDAMBV636 operates without requiring a minimum hydraulic pressure, adding to its versatility across various hydraulic systems. It includes manual override options with a detent mechanism designed for temporary actuation; the mechanical life expectancy of this manual control assembly is about 7,000 cycles. The valve also supports configurations with EPDM seals specifically for use with phosphate ester fluids; however, these seals are sensitive to petroleum-based fluids which can cause damage. Additionally, the DMDAMBV636 utilizes a wet armature design allowing the working fluid to cool the armature, suitable for applications where the coil may be energized continuously. The valve's design also supports interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. It incorporates Sun's floating style construction to minimize internal parts binding due to installation variations or machining discrepancies. 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 valve leakage at high pressures. The switching frequency can reach up to 15,000 cycles per hour. This model is engineered for precise control in hydraulic systems requiring reliable performance under high pressure and variable conditions.
