The Sun Hydraulics DMDADBN2E12V (DMDADBN2E12V) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust service with a fatigue rating of 5000 psi (350 bar). It features closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. The valve operates without requiring a minimum hydraulic pressure, adding to its versatility across various applications. The DMDADBN2E12V incorporates a wet armature design where the working fluid surrounds the armature. This design consideration is crucial as prolonged energization of the coil can lead to heat generation affecting fluid integrity, such as in water-glycol mixtures which may degrade and form varnishes impacting cartridge function. 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. Further enhancing its utility and ease of maintenance, the coils of this model are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The manual override feature equipped with D or L control uses a detent mechanism designed primarily for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. This model also benefits from Sun's floating style construction which minimizes internal parts binding due to excessive installation torque or cavity/cartridge machining variations. With a maximum operating pressure capability of 5000 psi (350 bar) and a flow capacity up to 12 gpm (45 L/min), the DMDADBN2E12V is an adaptable solution suited for demanding hydraulic applications requiring precise control and reliability.
