Danfoss DTD-14.7-7.7 D-Track Two Speed Axial Piston Motor
Product Information
The D-Track Two-speed axial piston motor is a durable and powerful track drive motor designed for various applications, including excavators. It features a two-speed design with displacements ranging from 14 cm3 to 185 cm3 [0.9 in3 to 11.3 in3] and a continuous pressure rating of 365 bar [5,294 psi]. The motor has an integrated design with a reducer, parking brake, and multi-functioning valves, providing high efficiency with smooth acceleration and deceleration. Customizable features include the shockless relief valve, counter-balance valve, anti-cavitation valve, and auto-two-speed function.
