Product Description

Continental Hydraulics’s Proportional Control Valve with on-board electronics (OBE) combines the precision of electronics with the ruggedness of hydraulics to stretch the performance of your machines. Designed for the way you work, Continental’s proportional control valve ensures accuracy and repeatability, which increases your system productivity.

Set-up is easy. The on-board electronics module is easily installed with a 7-pin connector cable that reduces machine wiring and simplifies setup. The dynamic performance, precision, and reliability of your machines are optimized using Setup parameters that are easily established through Windows Based Graphic User Interface.

All needed software is provided. Simply connect your laptop or PDA to the valve through an RS232 cable. The values are just a point and click away. The Setup Parameters include independent settings for single and dual solenoid valves, for Null or spool centering, Gain control, Acceleration and Deceleration, Dither control, and selection of Input Command. A Diagnostic window shows graphical and numerical; values of Solenoid Current, Input Signal and Sensor Feedback Signal for ease in troubleshooting. You can download this information into an Excel spreadsheet for simplified performance tracking and comparisons. When setup values are set, they can be stored and easily downloaded, to quickly set up additional machines.

The On-Board Electronic valves also incorporate the new Patented Hall Effect spool position sensor for closed inner-loop operation making the valve operate with minimal hysteresis and great repeatability performance.

Spool Selection

Hall Effect spool position sensor for closed inner loop operation Standard Mountings – NFPA and ISO Standard Selecting the correct spool is critical for best control in any application. An incorrectly sized spool can make the difference between consistent, reliable operation and poor overall control. Continental Hydraulic offers not only a wide variety of flow rates, but also offers a variety of metering functions. These metering functions are designed to match the load, actuator and circuit characteristics for the best possible control.

It is important to choose the correct spool for your application. Typically choose a spool that will pass the flow you need at approximately a 200 – 300 psid full loop pressure drop for best overall performance. Refer to the Flow Curve Charts if needed. This pressure drop and / or back pressure provides the needed system stiffness that is required for optimum control.

Features & Benefits

• On-Board Electronics Amplifiers help save control panel space and the costs of mounting
• The new GUI (Windows based Graphic User Interface) valve programming software allows complete set-up of all performance parameters as well as diagnostics in real time
• Proportional valves utilize the new patented Hall Effect spool position sensor for high accuracy
• Proportional products allow control over the load; higher speeds and accuracy can be obtained, increasing your production and profits
• All components that make up the valve including the OBE module can be purchased separately, no need replace the complete valve package if only one component fails
• Provide both direction and flow control in one component
• Eliminates need for multiple valves or the number of components saving costs
• Infinitely-variable control allows you flexibility over motion
• Provides acceleration and deceleration controllability
• Smooth no-shock motion reduces down time, increases production rates
