The Sun Hydraulics DMDAMPV828 (DMDAMPV828) 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), making it suitable for various demanding hydraulic applications. The valve features spools B and R which are closed during the transition between two positions, enhancing performance limits at the cost of lower capacity\u2014ideal for pilot controls where capacity is less critical but fast and consistent response times are necessary. The DMDAMPV828 operates without requiring a minimum hydraulic pressure, ensuring reliable performance in diverse operating conditions. It includes manual override options with detent mechanisms designed for temporary actuation, with an expected mechanical life of approximately 7,000 cycles. For systems utilizing phosphate ester fluids, this model can be configured with EPDM seals; however, these seals must not be exposed to petroleum-based fluids as they will degrade. Additionally, the valve incorporates a wet armature design where the working fluid surrounds the armature; this design consideration is crucial when the coil remains energized over extended periods as it can affect fluid integrity and valve functionality. The interchangeable coils compatible with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement. The construction features Sun\u2019s floating style design which minimizes internal parts binding due to installation or machining variations. This model has a flow capacity of 12 gpm (45 L/min), and it offers quick response times typically around 50 ms. It supports frequent switching up to 15,000 cycles per hour and comes equipped with manual override features that require minimal force. Its robust build quality and versatile specifications make it an essential component for systems requiring precise control over fluid direction and flow under high-pressure conditions.
