The Sun Hydraulics DMDAXPNHN24AB (DMDAXPNHN24AB) is a solenoid-operated, 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve features a fatigue rating of 5000 psi (350 bar), making it suitable for demanding applications. The valve operates with no minimum hydraulic pressure required and incorporates a wet armature design, where the working fluid surrounds the armature, potentially affecting fluid integrity under prolonged energization. The model is equipped with interchangeable coils from the Sun Series 1 solenoid products and can be mounted in either direction on the tube. It uses EPDM seals specifically for systems containing phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. The manual override feature, available in D, L, and T control models, has a mechanical life expectancy of about 7,000 cycles and is intended for temporary actuation. This valve offers a maximum flow capacity of 12 gpm (45 L/min) and features closed transitions between spool positions B and R to enhance performance by ensuring faster and more consistent response times at the expense of lower capacity. This makes it ideal for use as pilot controls in applications where capacity is less critical. The construction of the valve minimizes internal parts binding due to its Sun floating style design, accommodating installation torque and/or cavity-cartridge machining variations. Additional technical specifications include a maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, maximum valve leakage at 110 SUS (24 cSt) being 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar), and a switching frequency capable of reaching up to 15,000 cycles per hour. The manual override requires an actuation force of approximately 5 lbs at 1000 psi for Port 1.
