The Sun Hydraulics DMDAMNN636 (DMDAMNN636) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust and efficient hydraulic flow control. This direct-acting, balanced spool directional valve operates with a maximum pressure of 5000 psi (350 bar) and is fatigue rated for demanding applications. It features closed transitions between its two positions, Spools B and R, enhancing performance by ensuring faster and more consistent response times especially suitable for pilot control applications where capacity is less critical. The DMDAMNN636 utilizes a wet armature design allowing the working fluid to surround the armature, which can be critical when the coil remains energized over long periods as it might affect fluid integrity in certain conditions. The valve's manual override option is equipped with a detent mechanism designed for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. Additionally, it supports a range of manual control assemblies labeled as D, L, and T. For compatibility with different system fluids, cartridges configured with EPDM seals are specifically intended for use with phosphate ester fluids; however, they must avoid exposure to petroleum-based substances which could damage the seals. The interchangeability of coils within Sun's Series 1 solenoid products offers flexibility in maintenance and replacement procedures. Furthermore, this model incorporates Sun\u2019s floating style construction that minimizes internal parts binding due to installation torque or variations in cavity/cartridge machining. Key specifications include a flow capacity up to 12 gpm (45 L/min), typical response time of 50 ms, maximum valve leakage at 110 SUS (24 cSt) rated at 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar), and an operational switching frequency up to 15,000 cycles/hr. The valve also has specific requirements for manual override force and stroke that ensure precise control during operation.
