Seal Replacement for Dual Spool Control Valve
1. All hydraulic valves must be properly installed into the hydraulic system to prevent
personal injury and/or property damage. Further the improper servicing of a valve may
result in personal injury and/or property damage. Please read and understand all catalog
and service information before starting. As with all mechanical work the proper tools,
knowledge, and safety equipment are required. Always wear safety glasses
2. Make sure all pressure has been relieved in the hydraulic lines before installing or
servicing a hydraulic valve.
Escaping hydraulic fluid under pressure can have sufficient force to penetrate skin,
causing serious personal injury. Do not use your hand to check for hydraulic leaks.
3. Before installing or servicing a hydraulic component make sure all weight has been re-
moved from the cylinders or motors before disconnecting hydraulic lines.
4. Do not exceed the operating specifications for pressure, flow or temperature. All hydraulic
systems require a means to limit the maximum pressure. This requires either a pressure
relief valve in the system or a pump that has pressure compensation.
Disconnecting the hydraulic lines while the Cylinder or Motor is under pressure may
result in the unexpected rapid movement of machine resulting in serious personal injury.
Overpressure may cause sudden and unexpected failure of a component in the hydraulic
system resulting in serious personal injury. Always use a gauge when adjusting a relief
valve.
