Priority control

A priority valve is used when you want to provide the main function with a constant flow that remains unaffected by using extra outlets to other functions.

Priority valves for extra function or installation to tank through a shunt

Priority valves supply oil to a primary circuit. The main function is provided with a fixed preset flow and the remaining flow can be used for other functions, such as cylinders or attachment to a tank through a shunt.

Priority valves for stone crushers and hydraulic hammers

Sun Hydraulics offers several ready-made circuits for prioritizing flow, for example for additional functions such as stone crushers or hydraulic hammers for excavators, wheel loaders and other construction machines. These are simple and efficient circuits that ensure that no power is lost on the main function when an extra cylinder or engine is running.
