Check Valves & Injectors
Defined flow direction and precise dosing.
Key components for safe and precisely controlled fluid systems.
Process safety in detail
Often, it’s the seemingly inconspicuous components that play a decisive role in the safety and efficiency of an entire system. Our robust check valves ensure defined flow direction, while our precision injectors enable accurate media dosing.
1. Check valves (non-return valves)
Check valves – also referred to as non-return valves – ensure that media flows only in a defined direction. This protects system components from damage caused by unintended backflow and contamination.
2. Injectors (jet pumps)
Injectors operate based on the Venturi principle, using a motive fluid (e.g. water) to draw in and precisely dose a secondary medium (e.g. a concentrate). They are ideal for cleaning, disinfection and dosing applications.
