VALVES


Cut-off ball valves
Cut-off ball valves are used in supply and run-off units of powered mining roof supports. They are used for
passing and cutting off the flow of high pressured medium.

 

Threshold valves
Threshold valves enable medium flow in one direction and cut off the return. The flow cut off is automatic
when the balance of pressure forces appears on both sides of the valve.




Yield valves
The yield valves are used to limit pressure in hydraulic systems. The pressure limit is permanently set as
required. The valves are also used to protect the hydraulic system from any potential damage caused by
excessive pressure rise.
