The Sun Hydraulics DMDATRV71299 (DMDATRV71299) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. It features a direct-acting, balanced spool design that ensures reliable operation without the need for minimum hydraulic pressure. Ideal for applications requiring precise control and rapid response, this valve is particularly effective when used as pilot controls due to its closed transition between positions\u2014B and R spools are closed in the transition phase\u2014enhancing performance by ensuring faster and more consistent response times. With a maximum operating pressure of 5000 psi (350 bar) and a capacity of 12 gpm (45 L/min), the DMDATRV71299 is designed to handle demanding tasks efficiently. It incorporates a wet armature design where the working fluid surrounds the armature, which is critical in applications where the valve may be energized for extended periods. However, it's important to note that certain fluids may degrade under prolonged exposure to heat, potentially affecting valve performance. The construction of this model uses Sun\u2019s floating style to minimize internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This feature contributes significantly to its robustness and durability, with an expected mechanical life of around 7,000 cycles for models equipped with manual control assemblies like D or L controls. The manual override mechanism provided is intended primarily for temporary actuation. This valve also offers flexibility in maintenance and upgrades as its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Seal options include EPDM for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. The overall design and capabilities make the DMDATRV71299 an excellent choice for sophisticated hydraulic systems demanding high reliability and precise control.
