The Sun Hydraulics DMDAMPV648 (DMDAMPV648) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is specifically designed to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). The valve features closed transitions between spools B and R, enhancing performance by providing faster and more consistent response times in applications where capacity is less critical. This model is particularly suited for use as pilot controls in hydraulic systems due to its robust design that includes a wet armature configuration. The wet armature design ensures the working fluid surrounds the armature, which can be crucial in systems where the coil may be energized for extended periods. However, it's important to note that certain fluids such as water-glycol mixtures might degrade under prolonged exposure to heat. Additionally, the DMDAMPV648 comes with interchangeable coils compatible with other Sun Series 1 solenoid products and features a manual override mechanism designed for temporary actuation with an expected mechanical life of about 7,000 cycles. It also incorporates Sun\u2019s floating style construction which minimizes internal part binding due to installation torque or machining variations. For environments utilizing phosphate ester fluids, cartridges configured with EPDM seals are recommended; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. The manual override requires a force of approximately 5 lbs per 1000 psi at Port 1 for operation and allows for a stroke of .10 inches (2.5 mm). This model's robust build and versatile design make it an ideal choice for diverse hydraulic applications requiring reliable directional control and rapid response times.
