Error Prevention at the Source - Proportional Valve with On-Board Electronics

Error Prevention at the Source

OBE (On-Board Electronics) is the direct and best way to correct a nonlinear behavior of your valve. The sensor and electronics on the valve body implement a control loop at the front line of the system. Mechanical tolerances, friction, hysteresis and wear no longer cause failures in the movement of the drive. For a modern machine monitoring, the sensor information can also be sent to the main controller.

Advantages of implementing the proportional technology
Efficiency, speed, accuracy, low hysteresis, repeatability and the chance to adapt the control are the main benefits of introducing proportional technology in hydraulic applications. ARGO-HYTOS valves, combined with advanced electronics, are capable of meeting the demands posed by a large variety of stationary and mobile applications.
ARGO-HYTOS develops and manufactures proportional valves to provide its customers the chance to take full advantage of the benefits of proportional technology.
The new directional valves PRM9-06 and PRM9-10 with advanced electronics, design of the mechatronic parts along with a robust design make this possible.
