The Sun Hydraulics DMDAMPV836 (DMDAMPV836) is a solenoid-operated 3-way, 2-position cartridge valve, designed as a direct-acting, balanced spool directional valve. This model is specifically engineered to handle rigorous demands with a fatigue rating for 5000 psi (350 bar) service. The DMDAMPV836 features closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times during operation. This attribute makes it particularly effective when used as pilot controls where capacity is less critical. The valve operates without the need for minimum hydraulic pressure, facilitating its use in various applications. It incorporates a wet armature design that allows the working fluid to surround the armature; however, it's important to note that prolonged energization of the coil can lead to higher fluid temperatures which might affect certain fluid types. The DMDAMPV836 is compatible with EPDM seals suited for phosphate ester fluids but should avoid contact with petroleum-based substances to prevent seal damage. Interchangeability of coils with other Sun Series 1 solenoid products adds versatility to this model, and the coils can be mounted in either direction on the tube. Additionally, this valve utilizes Sun's floating style construction which minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and a typical response time of 50 ms. Manual override features require minimal force, making temporary actuation straightforward while ensuring durability with an estimated mechanical life expectancy of approximately 7,000 cycles for models equipped with manual control assemblies.
