The Sun Hydraulics DMDAXPN736 (DMDAXPN736) is a solenoid-operated 3-way, 2-position cartridge valve that functions as a direct-acting, balanced spool directional valve. Designed for robust performance, this model is fatigue rated for 5000 psi (350 bar), making it suitable for high-pressure applications. The valve features closed transitions between positions B and R, enhancing performance by ensuring faster and more consistent response times, particularly beneficial in pilot control applications where capacity is less critical. This direct-actuated valve operates without the need for minimum hydraulic pressure, facilitating reliable functionality across various conditions. It includes manual override options with D or L control, featuring a detent mechanism designed primarily for temporary actuation with a mechanical life expectancy of about 7,000 cycles. Notably, the valve utilizes EPDM seals configured specifically for use with phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based substances. The wet armature design of the DMDAXPN736 means that the working fluid envelops the armature which could be subject to heat during prolonged coil energization\u2014important to consider in thermal management of systems using water-glycol mixtures or similar fluids. Additionally, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Sun Hydraulics has incorporated their floating style construction into this model to minimize potential internal binding caused by excessive installation torque or variations in cavity/cartridge machining. With a maximum flow capacity of 12 gpm (45 L/min) and a rapid typical response time of 50 ms, along with minimal leakage and high switching frequency capabilities, this valve ensures efficient and reliable operation in demanding hydraulic systems.
