Back-pressure valves / pressure relief valves

Keeps the operating pressure of the pump constant

Back-pressure and pressure-relief valves are fittings for dosing systems Depending on the task involved, they are used to increase the dosing accuracy or to protect the system against too high pressure. If the delivery pressure is higher than the dosing pressure, dosing without a back-pressure valve is not possible.

  • Output range from 75 – 5000 l/h, up to 250 bar
  • Deployment in a potentially explosive atmosphere is possible (spring-loaded seat valve DN6 200 bar and DN10 250 bar)
  • Assembly in any installation location (only spring-loaded seat valves must be installed vertically)
  • Installation of a pressure-relief valve with return to the dosing tank possible
