Flow dividers – are devices which split the flow from a pump into two streams for independently operating two branch circuits. Advantages of flow divider operation are:
- Only one pump is required. This is a particular advantage in the saving of space, and reducing cost.
- Each branch circuit is isolated from the other: changing loads on one branch will not affect the pressure or flow in the other branch. Flow dividers are only for hydraulic systems; they are not applicable to most industrial air systems.
Spool-type dividers can be built to deliver proportional flows from two outlets, or to deliver a priority flow from one outlet with excess flow coming out the other outlet. Only the spool-type is manufactured by Hydraulic Projects.
When Are They Used?
Two general methods are used for dividing a flow of oil. One method uses a sliding spool; the other method uses rotary construction, and operates similarly to two gear-type pumps with shafts coupled together. The two gear sections meter proportional amounts of oil to each outlet.
They are used on agricultural and industrial machinery to control the speed of the bed chains or drums, and also in tracked vehicles to control the speed and direction of travel.
How Are They Made?
The body is aluminium, and the rest of the components are either hardened or nitro-carburised steel.
The action of spool-type and rotary-type dividers is quite different, and each requires a degree of technical knowledge to apply them properly and on suitable applications.
The product is manufactured in the UK, for excellent service and support. When combined with our solenoid controlled directional valves, they provide an economical alternative to full proportional control.
