PVDF Metering Valve Adapter
For the installation of injection valves into pipework with straight unions.
The adapter projects into the pipework or storage tanks and can be adjusted (shortened) at different cross-sections.
Direct contact of the chemical to be metered with the wall can be avoided by installation of the adapter. Metering into the centre of the pipework improves, among other things, the mixing through of the metering solution.
Material: PVDF

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!
Your benefits
- Used as a non-return valve – in closed pipe systems to prevent mixing and backflow into the metering line.
- Used as a back pressure generator – in systems with a free outlet, to generate a defined back pressure.
