Troubleshooting charts for eight categories of hydraulic problems The following troubleshooting guides cover five categories of hydraulic problems. Possible causes and remedies are listed for each type of trouble. Causes are listed in order of probability; remedies are listed adjacent to the associated cause. Abnormal / exessive noise

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.

Getting back to cylinder drift caused by the radial clearance of the directional control valve spool, if the pump can't be unloaded then a float

2007/2/9 · Screw-in cartridge valves perform all directional and flow control, relief, sequence, counterbalance and reducing functions -- the same as in-line and subplate valves. Only their physical makeup is different. They normally handle flows less than 40 gpm, but some manufacturers offer sizes with up to 120-gpm capacity.

Problem #1: Sticking/will not shift Most DCV valves use a sliding spool/bore design. When a valve sticks, the spool cannot change positions when an operator applies normal force. Several factors can cause this sticking action, including contamination, silting, mechanical failure or operator failure. Let's look at these common causes. Contamination

Directional valves control the direction that fluid flows. They start and stop the flow, or direct it along different pipelines. Directional valves are used to control the movement of hydraulic actuators, primarily cylinders or motors. This may be a single, hydraulic on/off switch to start and stop a hydraulic motor, or a 4-way, 3 position.
