within a conduction pipe line or hose line system characterised through an interlock element to either block, divert control or regulate the flow pattern of the hydraulic medium.
|The basic principles are the medium properties relating to the material (housing, cover/ surface, sealing), the approvals (DVGW) and the operating pressures (nominal pressure) as well as the temperatures.|
|Depending on the respective skills and expertise of the operator either a manual operation, an electromagnetic impulsion or a pneumatic rotary drive is applicable (positioning contact can also release switching impulses).|
|Standardised connexions allow a proper implementation into the hydraulic system. This however can only be achieved by considering the admissible working pressure, the temperature, the suitable sealing form, the choice of material as well as the occuring external stresses.|
