Non Return Valves

Brass Non Return Valves

Brass non return valves are used to prevent backflow in a system.  They are normally fitted close to the source and prevent the liquid running out of the system when the pump stops (or when pressure is lost)

  • These valves are typically fitted on (or near) a pump - preventing water draining out of the system, protecting the pump and ensuring that it remains primed
  • Occasionally they are used to prevent liquid passing in a certain direction, this is common for pump control:
    • E.g: in a 2 pump system, where the systems needs to be able to run in two modes:
      • one pump mode
      • Two pump mode

We offer a wide range of sizes for these non return valves, if you need help in selecting the right one, just give us a call or an email and our team will be happy to help.
