Differential Lock Valve: MT..DVV Quadruple

Series MT..DV hydraulic differential lock valves are used in open- and closed-loop circuits to drive parallel-connected hydraulic motors in hydrostatically driven vehicles. When the lock valve is switched off, the inlet flow can divide itself among the hydraulic motors in any required ratio, and with minimal pressure losses.

When the lock valve is switched on, the hydraulic motors are compelled to operate at the preset speed ratio. This arrangement prevents any hydraulic wheel motor from spinning in conditions of poor traction. A balancing orifice between the outlets prevents unwanted torque build-up between wheels in these circumstances.
