Proportional Valves
Precision Flow and Pressure Control for Demanding Hydraulic Systems
General Information
We supply a complete range of hydraulic proportional valves, both original and compatible versions, from leading global manufacturers such as Rexroth (Bosch Group), Parker, Hydac, Voss, Sun Hydraulics, and Stauff. These valves are designed to provide precise control of pressure and flow in hydraulic systems, enabling smooth and accurate actuation of cylinders, motors, and actuators.
Unlike traditional on/off valves, proportional valves allow continuous and variable adjustment based on electrical input signals, making them essential in modern automation and process control. They are widely used in industrial, mobile, and energy applications where fine pressure regulation, load sensing, and speed control are required.
Our product line includes direct-operated and pilot-operated proportional valves, with analog or digital electronics, available in different mounting styles (subplate, threaded, cartridge). We also provide engineering support to select the correct flow capacity, response time, and electronic configuration for OEM projects or retrofit solutions. All models are available with worldwide shipping and backed by technical assistance.
