Injection Valve and Non-Return valves for dosing pumps

Injection Valves / Non-Return Valves

We supply a range of replacement injection valves for use with our range of solenoid dosing pumps.  Each injection valve acts as a non-return valve so that when the injection valve is connected to the point on which the chemical reagent is to be delivered into the process, the chemical reagent can flow out, but the process solution cannot flow back up the delivery pipework.

Our injection valves are designed specially for use with chemical reagents and are available manufactured in either PVC or PVDF.  There are options on the seals and o-rings to ensure compatibility with the chemical reagent that you're using.

The non-return mechanism for each of the inception valves is manufactured with a Hastelloy-C spring with a ceramic ball valve.  PTFE coated alternatives are viable for concentrated chemical reagents that react with ceramic or Hastelloy-C.  As with all process equipment, we recommend that you check that the wetted parts are compatible with the chemical to be used by either checking our chemical compatibility database or speaking with your chemical supplier.

 

Fitting An Injection Valve

Each injection valve is designed for use with dosing tube and is either sized for the following tubing sizes:-

  • 4x6mm
  • 8x10mm
  • 8x12mm

The tubing is connected via a specially manufactured compression fitting and the process side contains a dual thread for both 3/8" BSP and 1/2" BSP.
