The Sun Hydraulics DMDAMRV2E12V (DMDAMRV2E12V) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve is notable for its fatigue rating of 5000 psi (350 bar), making it suitable for demanding operations. The valve features closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times especially in pilot control applications where capacity is less critical. This model operates without the need for a minimum hydraulic pressure, facilitating its use in a variety of system conditions. It includes manual override options with detent mechanisms designed primarily for temporary actuation; these mechanisms are expected to last approximately 7,000 cycles. The DMDAMRV2E12V is also equipped with EPDM seals appropriate for use with phosphate ester fluids, although these seals must not be exposed to petroleum-based substances which could cause damage. Moreover, the valve incorporates a wet armature design where the working fluid envelops the armature\u2014important to consider as prolonged energization can lead to fluid degradation at high temperatures. The interchangeable coils compatible with other Sun Series 1 solenoid products add to its versatility and ease of maintenance. Additionally, this model benefits from Sun's floating style construction that minimizes internal part binding due to installation torque or cavity/cartridge machining variations. With a maximum flow capacity of 12 gpm (45 L/min) and swift typical response times of 50 ms, coupled with maximum operating pressures up to 5000 psi (350 bar), this model ensures reliable and efficient operation across various hydraulic applications. Its design considerations such as switching frequency capable of reaching up to 15,000 cycles/hr further underline its capability for high-frequency usage scenarios.
