PVDF Metering Valve Adapter
For the installation of injection valves into pipework with straight unions. The adapter extends into the pipework or storage tank and can be adjusted (shortened) to various cross-sections. Direct contact between the chemicals being metered and the wall can be avoided by installing the adapter. Metering into the centre of the pipework improves how the metering solution is mixed and other aspects.
Material: PVDF
Application
25 °C - max. operating pressure 16 bar
65 °C - max. operating pressure 10 bar

Overview
The right support for every metering task
Injection valves are mounted at the point of injection to connect the metering line. They protect against backflow and generate a defined back pressure.
They are equipped with a check ball and a Hastelloy C spring (priming pressure approx. 0.5 bar). They may be fitted in any position.
Materials used as in the pump liquid ends. Injection valve sizes DN 10 and 15 are supplied with union nuts and inserts / hose nozzles.
Important: Injection valves are not absolutely leak-tight shut-off devices!
The benefits for you
- Used as a check valve – in closed pipe systems to prevent mixing and backflow into the dosing line.
- Used as a back pressure generator – in systems with a free drain, to generate a defined back pressure.
