Back-pressure valves / pressure relief valves
Keeps the Pump's working pressure constant
Pressure-relief valves and Pressure-relief valves are fittings for Dosing systems. Depending on the task, they are used to increase dosing accuracy or to protect the system against excessive pressure. If the inlet pressure is higher than the dosing pressure, dosing is not possible without Back-pressure valves.
- Nominal flow: 75 - 5000 l/h, up to 250 bar
- Can be used in potentially explosive atmospheres (spring-loaded seat valves DN6, 200 bar and DN10, 250 bar)
- Mounting position: any position (only spring-loaded globe valves must be mounted vertically)
- Installation of a Pressure-relief valves with return to the dosing tank possible
