### Slowing Down Hydraulic Cylinder Movement - Fluid Power ...

Well there's the answer! Your pump flow rate is 60 cubic inches per minute - that's less than 0.26 USGPM. Your flow control valve is actually a 3/8" NPTF pressure compensated flow control valve with reverse flow check and a quick check of the valve's datasheet shows that the MINIMUM setting of the valve is 1.0 US GPM.

### Basic Hydraulic Formulas | Flodraulic Group

### Hydraulic Pressure vs. Flow: Understanding the Difference

The pump delivers a rate of flow. The single function of the pump is to take fluid from one place and put it somewhere else. Pressure is the result of resistance to flow. In our training classes, we use the simple schematic shown above to explain this concept. A fixed-displacement pump is the simplest type of hydraulic pump.

### A Guide To Hydraulic Cylinders - Apex Hydraulics

Telescopic cylinders use a cylinder within a cylinder to increase the distance that can be lifted in one stroke. The stroke is the amount of lift that a cylinder is capable of in one movement. Typically used in machines such as tipping trucks, they can also be used within any fabrication that requires an increase in the stroke (the amount of movement that the cylinder generates), without ...
