How does a loader valve work?

A direct-acting, load-holding valve allows the load pressure to work against the full area of the poppet. As the operator lowers the load and directs flow to the bore end of the cylinder, pressure will be applied to the load control valve through the pilot line.

What happens if a hydraulic system leaks?

Besides high oil consumption, the economic effects of hydraulic system leakage include inefficient machinery operation, environmental damage, safety and accident liability, premature machine component failure, poor manufacturing quality and increased capital costs.
