Isolating a Proportional Solenoid Valve Problem

Isolating a Proportional Solenoid Valve Problem as Electrical or Mechanical Using a Bartol Mag- Probe

proportional solenoid valve

First, set the control on the circuit board to wide open.  This increases the voltage to the solenoid valves coil and cause the current to increase.  As a result, the magnetic field around the coil increases. Place the Mag-Probe’s tip near the coil until the LED in the Mag-Probe lights.  Slowly move the Mag-Probe’s tip away from the coil until the LED turns off, then move then Mag-Probe’s tip toward the coil until the LED turns on now you’re at the outer edge of the magnetic field. Now we know that the coil is good. The next step is to decrease the voltage to the coil by adjusting the control on the circuit board to the midpoint.  This will cause the magnetic field to decrease causing the LED to go out. Now move the Mag-Probe toward the coil until the LED turns on. This should be the midpoint of the solenoid valves opening. Then adjust the control on the circuit board to the off/close.  The magnetic field should turn completely off and the LED will go out.  Remember, the magnetic field should vary from large to medium and then zero as the control on the circuit board or from a remote location is switched.  If the valves port does not follow the magnetic field as observed in the electrical tests, the problem is mechanical.

This procedure can be accomplished in 5 minutes or less once the sequence is learned.

About the Author
Bob Bartol has spent his whole life working with electronics in almost every capacity and spent many hours in Physics classes. He currently holds 4 U.S. patents and has been making a living off one of the patents "The Bartol Mag-Probe" for over twenty years. Bartol Research's Mag-Probe now has a global reach and is dramatically reducing trouble shooting downtime anywhere a solenoid valve. relay, or contactor is used. F111 Air Force Projects - European Flight Competition January 1968 Bob attended electronics school in the Air Force. Upon graduation he was assigned to a fighter wing in Germany. During his assignment he prepared seven aircraft for European competition. The fighter wings aircraft won the competition. Bob then returned to the United States and taught advanced radar for two years. Two years later, he returned to Europe. During this assignment, Air Force headquarters Europe selected Bob to open a Precision Measuring Equipment Laboratory (P.M.E.L) in England. It was the first of its kind in the Air Force. Upon his return to the United States, Air Force headquarters assigned Bob to Air Force research command in Florida. This was strictly a scientific assignment for research and development. After three years he moved from Eglin AFB in Florida to Edwards Air Force Base in California where he had direct contact with the National Bureau of Standards and supported research and development aircraft. During this assignment, he designed a modification for the TF X fighter (F-111). This modification made possible an additional 9800 flying hours per year. The F111 was the first swing wing aircraft in history. General Dynamics completed the modification prior to acceptance by the U.S. Air Force. Modification of F111 Aircraft General Dynamics March 1968 As a result of increasing this flying time Bob Received an award from Edwards Air Force Base for Increasing flying time of the F111 by 9,800 hours per year. The Award was Presented by Colonel Grumbles to TSGT Bob Bartol on June 17, 1968
