Pressure-compensated hydraulic directional control valve KLSV series

sectionalfor high flow rates

Overview
KLSV series is a load-sensing control valve designed to manage actuators on construction and industrial vehicles. When paired with a variable displacement pump, it enables a closed-center load sensing hydraulic system, offering precise speed control independent of load conditions.

Features

• Flow Sharing (post-compensator) provides balanced and responsive actuator control.
• Low pressure loss reduces hydraulic energy consumption.
• High pressure capability allows for more compact and efficient system designs.
