To fix it, rotate the zero adjustment until the linear positioner stops drifting. If speed or positioning problems are occurring, the command and LVDT signals should be checked at the appropriate connections on the amplifier. If these are reading correctly, the problem is most likely in the hydraulic system or the linear positioner.

Because this type of valve controls the direction the hydraulic oil goes in, it is known as a directional control valve. Inside the spool valve, the spool controls to which work ports the fluid goes. The number of inlet ports from the hydraulic tank and pump and the number of outlets to various work locations indicate the type of valve.

A batch of hydraulic directional control valves he purchased last year had problems. Six months after shipment, the customer found that the hydraulic system could not operate because the valve spool of the hydraulic directional control valve was stuck, and asked ST company to solve it within 30 days. Peter communicated with the original

Troubleshooting Hydraulic Proportional Valves. Al Smiley, GPM Hydraulic Consulting. The cost of a proportional valve can be as much as 50 percent of the cost of a servo valve of the same size. However, servo valves continue to be used where precise positioning or speed control is required in aircraft, aerospace and turbine generator applications.

There are only 3 potential spool valve problems: external leakage, excessive internal leakage, or spool bind. External leakage due to seal failure can be
