"I am the Operations Manager at GPM Hydraulic Consulting and we have been using the Model PVT-02 proportional valve tester to troubleshoot proportional valves for our customers for many years now. We have purchased test boxes for all of our Consultants to use in the field when troubleshooting. This test box has saved us hours of troubleshooting and in return saved our customers hours of downtime. The box is connected in a series so you can observe the supply voltage, command signal and LVDT (linear variable differential transformer) feedback from the proportional valve while the system is running normally. You can also use the box instead of the PLC to drive the valve to see if the problem is the controller or valve itself. If you have proportional valves, you need to get one of these test boxes. Without the box to troubleshoot, your valves may get changed when there is nothing wrong with them. This box is also very affordable, a lot cheaper than what a proportional valve costs."

"I wanted to take a minute and thank you for a well done job in getting our new Scanner and set-works up and running after the install. Production improved 15% over our cam set-works. Yield has also improved. Please thank your whole team for a job well done.”
"Change can come with many challenges, especially new setworks. Jerry and the crew at Paw Taw John did their part in providing us with outstanding service and tech support to minimize those challenges. GREAT PEOPLE!!!"

"Last year I went on a consult for a company that made floor panels for BMW. A proportional valve is what controlled the press opening and closing but the press would not move. I connected the test box to their valve in series to watch the power supply, command and feed back voltages. When a command was given to lower the press, a power supply voltage of 22.6 volts was supplied to drive the valve amplifier. Normally the voltage should be 24 volts however, 22.6 was within the acceptable limits of operating the amplifier. The command voltage applied was 3.5 volts. The LVDT feedback voltage should have been 3.5 however, it was reading near 0 at .4 volts. This indicated that the main spool did not move. We then move the selector switch to drive the valve with the box. The voltage was increased to 10-volt manually. The LVDT feedback continued to read .4 volts indicating that the pilot valve shifted but the main spool did not. We removed the valve assembly and found that contamination had caused the spool to stick."
