The Sun Hydraulics DMDADRN2E12V (DMDADRN2E12V) is a solenoid-operated 3-way, 2-position cartridge valve that functions as a direct-acting, balanced spool directional valve. Designed to handle a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min), this valve is equipped to deliver high performance and reliability in various hydraulic applications. Its solenoid tube assembly is fatigue rated for demanding conditions, ensuring durability under continuous use. This model features closed transitions between spool positions B and R, which enhances performance by providing faster and more consistent response times, particularly beneficial when used as pilot controls where capacity is less critical. The valve operates without requiring a minimum hydraulic pressure, adding to its versatility across different hydraulic systems. For manual override operations, the DMDADRN2E12V includes detent mechanisms with an expected mechanical life of around 7,000 cycles. It also utilizes EPDM seals suitable for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. The wet armature design within the valve ensures the working fluid surrounds the armature which may be significant in applications where the coil remains energized over extended periods. The potential breakdown of certain fluids at high temperatures should be considered to avoid impacting the cartridge's functionality. Moreover, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Incorporating Sun's floating style construction minimizes internal parts binding that could result from excessive installation torque or variations in cavity/cartridge machining. This design feature aids in maintaining consistent operational efficiency and reliability.
