| | | | |
Float Valves | | | Float valves control fill-levels of inflow and outlet. If the fill-level in a container lowers, the float will also lower and open the valve by a a lever; so the medium can flow in. |
When the float reaches a defined level, the inflow closes again. Float-valves are available in various materials and with different types of opening.
| | | | |
Hose Pinch Valve | | | For media with unfavorable viscosity and, as the case may be with solids, its recommend the use of a hose pinch-valve. |
