Injection Valve for Low-Pressure Metering Pumps

Injection valves precisely meter the flow volumes in a line and are securely sealed from the environment.

Product description

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.

In the PP, PVC, PVDF and stainless steel versions, the injection valve with ball check is spring-loaded with a Hastelloy C spring, priming pressure approx. 0.5 bar (with R1/4 connector, spring made of stainless steel no. 1.4571, priming pressure approx. 1 bar). They may be fitted in any position.

The TT version without a spring is suitable for vertical installation from below. Valve springs can be retrofitted.

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.
